The need for this handbook is a direct consequence of a very large
accumulation of new theoretical and experimental data on nucleur
properties. The first five chapters are devoted to the presentation
of experimental and theoretical aspects of the following topics:
atomic masses of stable and radioactive nuclides; an intuitive way
to understand the empirical trends of masses, based on a
microscopic theory; Penning traps used as a modern mass
spectrometer of high resolving power, accuracy and sensitivity;
basic theoretical concepts and experimental techniques used to
measure the nucleur shape parameters; new decay modes by hadron and
cluster emission; the proton (p), and the beta-delayed particle
emissions: neutron (n), 2n, 3n, 4n, p, 2p, 3p, d, t, etc. This book
is intended for students and professionals in nuclear physics,
radioactivity, astrophysics, high- energy physics and elementary
particles. Also industrial applications of nuclear radiation,
nuclear medicine, and environmental science.

A treatment of the experimental techniques and instrumentation most
often used in nuclear and particle physics experiments as well as
in various other experiments, providing useful results and
formulae, technical know-how and informative details. This second
edition has been revised, while sections on Cherenkov radiation and
radiation protection have been updated and extended.
Expanding upon the ideas first proposed in his seminal book
Cosmical Magnetic Fields, Eugene N. Parker here offers the first
in-depth treatment of the magnetohydrodynamic theory of spontaneous
magnetic discontinuities. In detailing his theory of the
spontaneous formation of tangential discontinuities (current
sheets) in a magnetic field embedded in highly conducting plasma,
Parker shows how it can be used to explain the activity of the
external magnetic fields of planets, stars, interstellar gas
clouds, and galaxies, as well as the magnetic fields in laboratory
plasmas. Provocative and fascinating, Spontaneous Current Sheets in
Magnetic Fields presents a bold new theory that will excite
interest and discussion throughout the space physics community.
Nuclear physics between 1921 and 1947 shaped more than any other
science thepolitical landscape of our century and the public
opinion on physical research. Using quantitative scientometric
methods, a new branch in the history of science, the author focuses
on the developments of nuclear physics in these formative years
paying special attention to theimpact of German emigrants on the
evolution of the field as a cognitive and social unity. The book is
based on a thorough analysis of various citation analyses thus
producing results that should be more replicable and more
objective. The scientometric techniques should complement the more
qualitative approach usually applied in historical writing. This
makes the text an interesting study also for the historian in
general.
Ever since the late 1930s, scientists have been sharply divided on
the question of atomic energy. It is hardly surprising, then, that
the American public is so apprehensive about its use. Hack M. Holl,
former chief historian a the U.S. Department of Energy,
characterizes the furor over nuclear energy as "one of the great
debates in American history." In this second edition of The
American Atom, the editors have updated the collection of primary
documents that tell the story of atomic energy in the United States
from the discover of fission through the development of nuclear
weapons, international proliferation, and attempts at control.
Anyone interested in the evolution of the issues will want to
examine the book's major sections on the Manhattan Project, the
Oppenheimer Case, the hydrogen bomb, nuclear testing and the test
ban, proliferation, arms control, and the strategy of deterrence.
For over 60 years, scientists and engineers have been trying to
crack a seemingly intractable problem: how to build practical
devices that exploit nuclear fusion. Access to electricity has
facilitated a standard of living that was previously unimaginable,
but as the world’s population grows and developing nations
increasingly reap the benefits of electrification, we face a
serious global problem: burning fossil fuels currently produces
about eighty percent of the world's energy, but it produces a
greenhouse effect that traps outgoing infrared radiation and warms
the planet, risking dire environmental consequences unless we
reduce our fossil fuel consumption to near zero in the coming
decades. Nuclear fusion, the energy-producing process in the
sun and stars, could provide the answer: if it can be successfully
harnessed here on Earth, it will produce electricity with near-zero
CO2 byproduct by using the nuclei in water as its main fuel. The
principles behind fusion are understood, but the technology is far
from being fully realized, and governments, universities, and
venture capitalists are pumping vast amounts of money into many
ideas, some highly speculative, that could lead to functioning
fusion reactors. This book puts all of these attempts
together in one place, providing clear explanations for readers who
are interested in new energy technologies, including those with no
formal training in science or engineering. For each of the many
approaches to fusion, the reader will learn who pioneered the
approach, how the concept works in plain English, how experimental
tests were engineered, the future prospects, and comparison with
other approaches. From long-established fusion technologies to
emerging and exotic methods, the reader will learn all about the
idea that could eventually constitute the single greatest
engineering advance in human history.

This volume contains the lectures presented by invited speakers at
the IV La Rlibida International Summer School on Nuclear Physics.
This was the IV edition of a summer school organized by our group
every three years on topics related to nuclear physics. This Summer
School was aimed mainly at young nuclear physicists, both
theoreticians and experimentalists, engaged in research work at
predoctoral or recent postdoctoral level. The topics treated in the
three previous editions of the School were: "Heavy Ion Collisions,"
"Theory of Nuclear Structure and Reactions" and "Nuclear As
trophysics." This year's School was entitled "Nuclear Physics at
the Borderlines." Special emphasis was placed on those topics along
which nuclear physics is ex pected to develop in the next few
years. The aim of the School was to provide the attendants with an
opportunity to get into close contact with experienced researchers
and listen to their account of the present state-of-the-art in
nuclear physics and the main future lines of development."
Quark-Gluon Plasma (QGP) is a state of matter predicted by the
theory of strong interactions - Quantum Chromodynamics (QCD). The
area of QGP lies at the interface of particle physics, field
theory, nuclear physics and many-body theory, statistical physics,
cosmology and astrophysics. In its brief history (about a decade),
QGP has seen a rapid convergence of ideas from these previously
diverging disciplines. This volume includes the lectures delivered
by eminent specialists to students without prior experience in QGP.
Each course thus starts from the basics and takes the students by
steps to the current problems. The chapters are self-contained and
pedagogic in style. The book may therefore serve as an introduction
for advanced graduate students intending to enter this field or for
physicists working in other areas. Experts in QGP may also find
this volume a handy reference. Specific examples, used to elucidate
how theoretical predictions and experimentally accessible
quantities may not always correspond to one another, make this book
ideal for self-study for beginners. This feature will also make the
volume thought-provoking for QGP practitioners.
Rapid progress in quantum theory brings us new important results
which are often not immediately clear to all who need them. But
fortunately, this is also followed by simplifications and
unifications of our previous concepts. The inverse problem method
("The most beautiful idea of the XX-th century" - Zakharov et aI.,
1980) has just both these aspects. It is rather astonishing that it
took 50 years after the foundation of quantum mechanics for the
creation of the "pictures" showing the direct connection of obser
vables with interactions. Recently, illustrations of this type
began to appear in the literature (e. g., how potentials are
deformed with thc shift of one energy level or change of some
resonance reduced width). Although they are transparent to those
studying the quantum world and can be included within the necessary
elements of quantum literacy, they are still largely unknown even
to many specialists. For the first time, the most interesting of
these pictures enriching our quantum intuition are col lected here
and placed at your disposal. The readers of this monograph have the
advantage of getting the latest information which became available
after the publication of the Russian edition. It has been incor
porated here in the simplest presentation possible. For example,
new sections con cerning exactly solvable models, including the
multi-channel, multi-dimensional ones and with time dependent
potentials have been added. The first attempts in solving the
three-body inverse problem are also mentioned."
A graduate-level one-volume textbook and reference work on the
structure and physics of atomic nuclei. Throughout this book the
underlying emphasis is on how a nucleus is constituted through the
interaction between the nucleons. The book is structured into three
parts: the first part contains a detailed treatment of the
two-nucleon force and of basic model-independent nuclear
properties; the second part discusses the experimental results of
nuclear models and their bases in fundamental theory; the third
part deals in some detail with alpha-decay and fission.
The second edition of this highly successful, original text discusses the production and characterization of X-rays. The book focuses on the fundamentals of X-ray physical properties from an experimental viewpoint. SI units are used throughout and the material has been updated thoroughly to reflect the changes in the use of X-rays and recent developments in the field. The text begins with a survey of work conducted before 1945. Continuous and characteristic spectra are discussed, followed by a description of techniques used in their study. Further studies of production, absorption and scattering in atomic and nuclear processes are described, including a completely new chapter on X-ray production by protons, alpha-particles and ions.
Results important for the general understanding of nuclear
structure have emerged from the study of the nuclei in the mass
region around the neutron-deficient and neutron-rich Zirconium
isotopes. This research report gives the proceedings of a workshop
which brought together about 70 experts in the area. Review papers
deal with the theoretical interpretation of the unusual properties
of these medium-mass nuclei, using the mean field approach, a
microscopic description, the interacting boson model and particle
rotor calculations. Papers also discuss experimental procedures for
studying nuclei far from stability and the possibility of complete
spectroscopy. The reviews are supplemented by short contributions
presenting very new results. Phenomena discussed include the
interplay between subshell effects and the strong proton-neutron
interaction in determining nuclear shape, the coexistence of
different nuclear shape and the occurrence of fast beta decay.
The fundamental model of nuclear structure is the shell model.
However, its application has been limited to light nuclei (up to
the sd shell) or heavier nuclei with only a few valence nucleons
outside closed shells. Its application beyond these limits has been
prohibited so far by the large scale of the calculations involved.
For the description of nuclei beyond the sd shell having several
valence nucleons the introduction of collective models becomes
necessary. The first comprehensive phenomenological model of
nuclear structure was the geometric collective model of A. Bohr and
B.R. Mottelson. An alternative approach was proposed in 1974 by A.
Arima and F. Iachello, known as the Interacting Boson Model. This
model, which uses group theoretical techniques in the description
of nuclear collective properties, has the advantage of relative
simplicity, allowing for detailed calculations of the properties of
even medium and heavy nuclei which cannot be reached by the shell
model yet. Several extensions and generalizations of the model have
appeared over the last decade. Algebraic descriptions for the
effects of clustering, permanent octupole deformation, and giant
resonances have also been given. For the description of odd nuclei
the Interacting Boson-Fermion Model has been introduced, and
nuclear supersymmetries associated with it have been analysed. The
present text is designed to provide physicists with an accessible
introduction to the subject.
Nuclear astrophysics is, in essence, a science that attempts to
understand and explain the physical universe beyond the Earth by
studying its smallest particles. "Cauldrons in the Cosmos," by
Claus E. Rolfs and William S. Rodney, serves as a basic
introduction to these endeavors. From the major discoveries in the
field to a discussion of the makeup of stars to an explanation of
standard lab techniques, this text provides students and scientists
alike a thorough and fascinating survey of the accomplishments,
goals, and methods of nuclear astrophysics. A classic in its field,
"Cauldrons in the Cosmos" will surely remain an important reference
in nuclear astrophysics for years to come.
"One could not wish for a better account of the current state of
knowledge (and uncertainty) about nuclear reactions in stars."--B.
E. J. Pagel, "Nature
""Written in an informal style that those uninitiated into the
jargon of nuclear astrophysics and astronomy will find readable and
illuminating. . . . A useful and long-awaited introduction to
nuclear astrophysics."--G. J. Mathews, "Science
"
