Die beruhmte Vorlesung von Freeman Dyson - nun erstmals auf Deutsch. In den 1940er Jahren zeigte Freeman Dyson die Aquivalenz zwischen den beiden Formulierungen der QED - des Pfadintegralansatzes von Richard Feynman und der Variationsmethoden von Julian Schwinger - und bewies somit die Konsistenz der QED. Dieses Buch beinhaltet die wertvollen - nie zuvor auf Deutsch publizierten - Vorlesungen uber Quantenfeldtheorie, die Dyson an der Cornell Universitat 1951 gehalten hat.

Der Theoretiker Edwin Thompson Jaynes bemerkte dazu: "Fur eine Generation von Physikern waren diese Vorlesungen ein Gewinn: klarer und besser motiviert als Feynmans Vorlesungen, und schneller und kompakter als Schwingers." Zukunftige Leser werden diese Vorlesungen ebenfalls mit grossem Genuss lesen und von dem klaren Stil profitieren, der fur Dyson stets so charakteristisch gewesen ist.

During the last several decades, the study of nuclear shapes has been of prime importance. A large number of investigations, both theoretical and experimental, have led to the discovery of a rich variety of nuclear shapes like, the basic spherical, deformed, superdeformed, triaxial, shape coexistence, reflection asymmetric (pear-shape) and other exotic ones. Apart from common nuclear structural properties, each of the mentioned shapes manifests properties associated with its specific form. It is interesting to note that most deformed nuclei are prolate deformed. In this monograph, attention is paid to pear-shaped nuclei.

From the Nobel Prize winning physicist who developed the famous uncertainty principle, Nuclear Physics provides an in-depth look at the study of the atom. The book was compiled from a series of Heisenberg s lectures on the subject, and it is detailed and accessible enough for anyone interested in the subject. Heisenberg begins with a short history of atomic physics before delving into the theory of the processes and reactions within the atom. Nuclear Physics is an essential book to understanding the atom, giving readers an unparalleled look at nuclear physics from one of the greatest scientific minds of the twentieth century. A controversial WWII figure, Werner Heisenberg was a German physicist. Born in 1901 to an academic family, Heisenberg was interested in scientific and philosophical pursuits from a young age. After graduating from the University of Munich, where he studied under physicist Arthur Sommerfield, Heisenberg went on to establish a career in the study of atomic and particle theory. He won the Nobel Prize in 1932 for his Uncertainty Principle. Heisenberg was one of the top German scientists during World War II, and he worked as the director of the German Uranium Project developing an atomic bomb for Germany. He did not succeed in this effort, however, before the end of the war. He was incarcerated from 1945 46 for his role in the Nazi regime, but in the 50s and 60s, Heisenberg continued to contribute his research to the field of nuclear physics. He retired in 1970 and resided in Munich until his death in 1973.

Equipment Qualificiation for Nuclear Installations: IAEA Safety Standards Series No SSG-69

Probabilistic fault displacement hazard analysis (PFDHA) is a relatively new methodology, and actual examples of applications are quite limited. The current publication provides an introduction to probabilistic approaches to fault displacement hazard assessment with reference to relevant IAEA safety standards. It delineates the most important aspects of PFDHA (including up to date practices, open problems, and challenging issues) within a coherent framework. The information provided will be valuable not only for Member States when applying PFDHA to the site safety assessment of existing installations, but also for nuclear power plant operating organizations, regulatory bodies, vendors, technical support organizations and researchers working in the area of seismic hazard assessmen

This publication presents the outcome of an IAEA coordinated research project (CRP) on methodologies for assessing pipe failure rates in advanced water cooled reactors. The goal of the CRP was to provide Member States with a strong technical basis for establishing nuclear power plant piping reliability parameters. To meet this goal two parallel and interrelated activities were carried out. In a first CRP activity, the participating institutions performed a series of benchmark studies. These studies, as described in this publication, were formulated for the purpose of evaluating different methodologies when applied to a common problem. The results were compared, and the reasons for differences were identified. This publication provides a description of the benchmark studies, the participants' individual methodologies applied, and simulations and analyses carried out, an independent synthesis of the results, and the main insights and conclusions from the exercise.

Das essential beschreibt die Planung und Konzeption sowie den Bau und Einsatz eines kleinen Beschleunigers, der in erster Linie Schul- und Lehrzwecken dient. Neben einer Funktionsbeschreibung wird insbesondere auf diejenigen Teilsysteme eingegangen, die fur den Betrieb eines Zyklotrons notwendig sind. Das essential vermittelt also dem Leser in nachvollziehbaren Schritten einen vertieften Einblick in die Funktion und das Zusammenwirken aller Komponenten eines Zyklotrons. COLUMBUS ist aber nicht nur ein Zyklotron FUER, sondern auch eines VON Schulern und Studenten, die in jeder Phase in die Entwicklung und den Bau miteinbezogen wurden. Im essential wird dies durch den teilweise verwendeten Dialogstil an den entsprechenden Stellen zum Ausdruck gebracht.

In einer quellenbasierten Studie gibt die Wissenschaftshistorikerin und Physikerin An Rettig einen lebendigen Einblick in das Streben von Heisenberg und Pauli nach einer einheitlichen Quantenfeldtheorie - von den Anfangen am Rande der Solvay-Konferenz 1927 bis zur Veroeffentlichung eines gemeinsamen Ansatzes und Paulis Tod 1958. Die Studie umfasst die Grundlagen, die Entwicklung und die physiktheoretischen Inhalte von Heisenbergs und Paulis Ansatz von 1958 und untersucht die Grunde fur dessen starke Ablehnung. Die Autorin berucksichtigt neben den physikalischen auch die zwischenmenschlichen Aspekte sowie den tiefen Wandel in der Physiker-Gemeinde uber die Vorstellung, was eine erfolgreiche Physik ausmacht und wie diese entstehen kann.

• Relates observed nuclear properties to the underlying nuclear interaction and the symmetry principles governing subatomic particles
• Regroups material and appendices to make the text easier to use
• Lists Internet links to essential databases and research projects
• Features end-of-chapter exercises using real-world data.

Introductory Nuclear Physics, Second Edition is an ideal text for courses in nuclear physics at the senior undergraduate or first-year graduate level. It is also an important resource for scientists and engineers working with nuclei, for astrophysicists and particle physicists, and for anyone wishing to learn more about trends in the field.

In the50years since the first volume of "Progress in Optics" was published, optics has become one of the most dynamic fields of science. The volumes in this series that have appeared up to now contain more than 300 review articles by distinguished research workers, which have become permanent records for many important developments, helping optical scientists and optical engineers stay abreast of their fields.
Comprehensive, in-depth reviewsEdited by the leading authority in the field"

Lars Reichwein untersucht die Struktur des beschleunigten Elektronenbundels im Bubble-Regime auf numerischem Wege und leitet analytische Skalierungsgesetze her. Durch die fokussierenden Effekte der ausseren elektromagnetischen Felder und der repulsiven Coulomb-Wechselwirkung entstehen regelmassige Coulomb-Cluster, genannt Wigner-Kristalle. Deren Aufbau ist von besonderem Interesse, da Wakefield-Beschleunigung eine aussichtsreiche Alternative zu herkoemmlichen Beschleunigungsmethoden darstellt, um auf moeglichst kurzen Beschleunigungsstrecken hohe Teilchenenergien zu erhalten.

Das vorliegende Buch beschaftigt sich mit statistischer Datenanalyse fur Studierende der Physik: Fehlerrechnung, Gauss-Verteilung, Zahlstatistik mit Binomial- und Poisson-Verteilung. Es wird einerseits Grundwissen behandelt, welches zum Verstandnis statistischer Aussagen notwendig ist, andererseits aber fur die praktische Arbeit bei der Datenanalyse Rezepte und Methoden bereitgestellt. Leser finden schnell zu erfassende Antworten auf Probleme der statistischen Datenanalyse des Experimentalphysikers und eine knappe, mathematische Formulierung. Die Methoden werden durch zahlreiche Beispiele aus der Praxis illustriert. Neben zahlreichen UEbungsaufgaben gibt es auch Programmieraufgaben, die mit einem leistungsfahigen Programm zur statistischen Datenanalyse geloest werden koennen und sich an der taglichen Arbeit von Physikerinnen und Physiker orientieren. Dieses Buch entstand aus einer Statistikvorlesung fur Studierende der Physik, die der Autor viele Jahre an verschiedenen Universitaten gehalten hat. Es richtet sich an Studierende der Physik - egal ob im Grundstudium, bei dem sie ab dem ersten Physikpraktikum mit statistischer Datenanalyse konfrontiert werden, oder im fortgeschrittenem Studium im Rahmen von Studien-, Abschluss- oder Forschungsarbeiten, bei denen statistische Verfahren benutzt werden. In der Neuauflage wurde das Buch um Kapitel u.a. zu Gauss-Markow-Theorem, Minimum-Chiquadrat-Fit und gewichteten Daten erganzt.

The identification and assessment of threats provides an essential basis for the selection, design, and implementation of nuclear security measures. For nuclear material and other radioactive material that is under regulatory control, and associated facilities and activities, the results of this identification and assessment are expressed as a design basis threat or representative threat statement describing the intentions and capabilities of potential adversaries against which the materials and associated facilities and activities are to be protected. An Implementing Guide was issued in 2009 under the title of Development, Use and Maintenance of the Design Basis Threat which was updated and revised. The result of this revision is the current publication. It provides a step-by-step methodology for conducting a national nuclear security threat assessment including both physical and computer security aspects, and for the development, use and maintenance of design basis threats and representative threat statements.

This book provides a systematic and comprehensive introduction to the neutronics of advanced nuclear systems, covering all key aspects, from the fundamental theories and methodologies to a wide range of advanced nuclear system designs and experiments. It is the first-ever book focusing on the neutronics of advanced nuclear systems in the world. Compared with traditional nuclear systems, advanced nuclear systems are characterized by more complex geometry and nuclear physics, and pose new challenges in terms of neutronics. Based on the achievements and experiences of the author and his team over the past few decades, the book focuses on the neutronics characteristics of advanced nuclear systems and introduces novel neutron transport methodologies for complex systems, high-fidelity calculation software for nuclear design and safety evaluation, and high-intensity neutron source and technologies for neutronics experiments. At the same time, it describes the development of various neutronics designs for advanced nuclear systems, including neutronics design for ITER, CLEAR and FDS series reactors. The book not only summarizes the progress and achievements of the author's research work, but also highlights the latest advances and investigates the forefront of the field and the road ahead.

Lise Meitner (1878-1968) was a pioneer of nuclear physics and co-discoverer, with Otto Hahn and Fritz Strassmann, of nuclear fission. Braving the sexism of the scientific world, she joined the prestigious Kaiser Wilhelm Institute for Chemistry and became a prominent member of the international physics community. Of Jewish origin, Meitner fled Nazi Germany for Stockholm in 1938 and later moved to Cambridge, England. Her career was shattered when she fled Germany, and her scientific reputation was damaged when Hahn took full credit - and the 1944 Nobel Prize - for the work they had done together on nuclear fission. Ruth Sime's absorbing book is the definitive biography of Lise Meitner, the story of a brilliant woman whose extraordinary life illustrates not only the dramatic scientific progress but also the injustice and destruction that have marked the twentieth century.

Dieses Lehrbuch bietet Studierenden der Physik eine Einfuhrung in die Quantenfeldtheorie und die Grundlagen des Standardmodells der Teilchenphysik. Ausgehend von den Inhalten, die in den Grundvorlesungen zur Theoretischen Physik im Bachelorstudiengang vermittelt werden, schlagt das Buch eine Brucke von der relativistischen Quantenmechanik uber die klassische Feldtheorie zur Quantenfeldtheorie und deren Anwendung auf die im Standardmodell vereinigten fundamentalen Wechselwirkungen zwischen Elementarteilchen. Sukzessive werden die elektromagnetische, die starke und die schwache Wechselwirkung phanomenologisch eingefuhrt, als Quantenfeldtheorie formuliert und ihre experimentelle UEberprufung diskutiert. Mithilfe von Zusammenfassungen und UEbungsaufgaben am Ende jedes Kapitels koennen Leser den Inhalt Revue passieren lassen und das erlernte Wissen anwenden. Schritt fur Schritt wird so das Standardmodell der Teilchenphysik entwickelt. Dieses stellt, spatestens mit der Entdeckung des Higgsteilchens im Jahre 2012 am CERN in Genf, eine vollstandige, in sich geschlossene Theorie der bis 2018 experimentell uberpruften Teilchenphysik dar. Das Buch ermoeglicht schon Studierenden am Ende des Bachelors die Theorie und deren faszinierende Prazision nachzuvollziehen.

This book summarizes the recent development of nuclear science as an important part of mesoscopic physics, the intermediate world between the macroscopic and microscopic. This fast developing area with many practical applications includes complex atoms, molecules (including biological), nuclei, small-scale solid state systems, and future quantum computers. The complexity of the problem appears due to the richness of problems, from the necessity to study individual quantum levels, to the fundamental features of statistics and thermodynamics.

Marie Curie coined the term 'radioactivity', and it is to her and her husband, Pierre Curie, that we owe much of our current understanding of the very fabric of reality. Born in Warsaw, Marie was the fifth and youngest child of teachers. Her father taught mathematics and science, for which she showed an early affinity, and she later went to study in Paris, where she met Pierre. The work they did together revolutionized modern science. As well as discovering the atomic rather than chemical nature of radioactivity, the Curies isolated two new elements: polonium and radium. This biography does full justice to the scientific and human aspects of Marie's life, detailing her tumultuous personal history at a time of social upheaval, and her struggle to gain recognition in an era when female scientists were almost unknown. Marie Curie died in 1934, succumbing to aplastic anaemia that may have stemmed from her scientific investigations. Her work not only contributed to our understanding of the structure of the atom - and therefore the structure of the physical world itself - but also laid the foundations for modern medical innovations such as radiotherapy. Her example continues to inspire millions of people across the world.
