This comprehensive text presents not only a detailed exposition of
the basic principles of nuclear physics but also provides a
contemporary flavour by covering the recent developments in the
field. Starting with a synoptic view of the subject, the book
explains various physical phenomena in nuclear physics along with
experimental methods of measurement. Nuclear forces as encountered
in two body problems are detailed next followed by the problems of
radioactive decay. Nuclear reactions are then comprehensively
explained along with the various models of reaction mechanism. This
is followed by recent developments like the pre-equilibrium model
and heavy ions induced reaction.
The book bridges the gap between a course on modern physics and an
advanced formal treatise on nuclear physics. The treatment of
topics is simple and direct. Physical ideas are given prominence
and this has been done by informal discussions and many analogies.
It starts with the tools of nuclear physics, both experimental and
mathematical. The author has taken special care in treating the
nuclear shell model throughout the analogy with atomic and
molecular physics. It is a suitable text for any student who has
been exposed to a college level course in modern physics and who
has mathematical competence at the level of calculus and elementary
vector analysis. An important feature of the book is that numerous
illustrative examples have been given along with 200 neatly drawn
figures and problem question sets.
A series of seminal technological revolutions has led to a new
generation of electronic devices miniaturized to such tiny scales
where the strange laws of quantum physics come into play. There is
no doubt that, unlike scientists and engineers of the past,
technology leaders of the future will have to rely on quantum
mechanics in their everyday work. This makes teaching and learning
the subject of paramount importance for further progress. Mastering
quantum physics is a very non-trivial task and its deep
understanding can only be achieved through working out real-life
problems and examples. It is notoriously difficult to come up with
new quantum-mechanical problems that would be solvable with a
pencil and paper, and within a finite amount of time. This book
remarkably presents some 700+ original problems in quantum
mechanics together with detailed solutions covering nearly 1000
pages on all aspects of quantum science. The material is largely
new to the English-speaking audience. The problems have been
collected over about 60 years, first by the lead author, the late
Prof. Victor Galitski, Sr. Over the years, new problems were added
and the material polished by Prof. Boris Karnakov. Finally, Prof.
Victor Galitski, Jr., has extended the material with new problems
particularly relevant to modern science.
Dalton's theory of the atom is generally considered to be what made
the atom a scientifically fruitful concept in chemistry. To be
sure, by Dalton's time the atom had already had a two-millenium
history as a philosophical idea, and corpuscular thought had long
been viable in natural philosophy (that is, in what we would today
call physics).
Atoms in Chemistry will examine episodes in the evolution of the
concept of the atom, particularly in chemistry, from Dalton's day
to our own. It begins with an overview of scientific atomic
theories from the 17th through 20th centuries that analyzes
corpuscular theories of matter proposed or entertained by natural
philosophers in the 17th century. Chapters will focus on
philosophical and religious conceptions of matter, 19th-century
organic structural theories, the debate surrounding the truth of
the atomic-molecular theory, and physical evidence accumulated in
the late 19th and early 20th centuries that suggested that atoms
were actually real, even if they were not exactly as Dalton
envisioned them. The final chapter of this book takes the reader
beyond the atom itself to some of the places associated with the
history of scientific atomism. As a whole, this volume will serve
as a passport to important episodes from the more than 200-year
history of atoms in chemistry.

Practically every display technology in use today relies on the
flat, energy-efficient construction made possible by liquid
crystals. These displays provide visually-crisp, vibrantly-colored
images that a short time ago were thought only possible in science
fiction. Liquid crystals are known mainly for their use in display
technologies, but they also provide many diverse and useful
applications: adaptive optics, electro-optical devices, films,
lasers, photovoltaics, privacy windows, skin cleansers and soaps,
and thermometers. The striking images of liquid crystals changing
color under polarized lighting conditions are even on display in
many museums and art galleries - true examples of 'science meeting
art'. Although liquid crystals provide us with visually stunning
displays, fascinating applications, and are a rich and fruitful
source of interdisciplinary research, their full potential may yet
remain untapped.
It was not until 1971 that the authority for defining scientific
units, the General Conference of Weights and Measures got around to
defining the unit that is the basis of chemistry (the mole, or the
quantity of something). Yet for all this tardiness in putting the
chemical sciences on a sound quantitative basis, chemistry is an
old and venerable subject and one naturally asks the question, why?
Well, the truth is that up until the mid-1920s, many physicists did
not believe in the reality of molecules. Indeed, it was not until
after the physics community had accepted Ernest Rutherford's 1913
solar-system-like model of the atom, and the quantum mechanical
model of the coupling of electron spins in atoms that physicists
started to take seriously the necessity of explaining the chemical
changes that chemists had been observing, investigating and
recording since the days of the alchemists.
This book provides a brief exposition of the principles of beam
physics and particle accelerators with an emphasis on numerical
examples employing readily available computer tools. However, it
avoids detailed derivations, instead inviting the reader to use
general high-end languages such as Mathcad and Matlab, as well as
specialized particle accelerator codes (e.g. MAD, WinAgile,
Elegant, and others) to explore the principles presented. This
approach allows readers to readily identify relevant design
parameters and their scaling. In addition, the computer input files
can serve as templates that can be easily adapted to other related
situations. The examples and computer exercises comprise basic
lenses and deflectors, fringe fields, lattice and beam functions,
synchrotron radiation, beam envelope matching, betatron resonances,
and transverse and longitudinal emittance and space charge. The
last chapter presents examples of two major types of particle
accelerators: radio frequency linear accelerators (RF linacs) and
storage rings. Lastly, the appendix gives readers a brief
description of the computer tools employed and concise instructions
for their installation and use in the most popular computer
platforms (Windows, Macintosh and Ubuntu Linux). Hyperlinks to
websites containing all relevant files are also included. An
essential component of the book is its website (actually part of
the author's website at the University of Maryland), which contains
the files that reproduce results given in the text as well as
additional material such as technical notes and movies.
The effect which now bears his name, was discovered in 1958 by
Rudolf Moessbauer at the Technical University of Munich. At first,
this appeared to be a phenomenon related to nuclear energy levels
that provided some information about excited state lifetimes and
quantum properties. However, it soon became apparent that
Moessbauer spectroscopy had applications in such diverse fields as
general relativity, solid state physics, chemistry, materials
science, biology, medical physics, archeology and art. It is the
extreme sensitivity of the effect to the atomic environment around
the probe atom as well as the ability to apply the technique to
some interesting and important elements, most notably iron, that is
responsible for the Moessbauer effect's extensive use. The present
volume reviews the historical development of the Moessbauer effect,
the experimental details, the basic physics of hyperfine
interactions and some of the numerous applications of Moessbauer
effect spectroscopy.
Electrostatic forces are essential for the hierarchical structure
of matter: electrons are bound to the atomic nucleus by
electrostatic forces; atoms carry (partial) charges and ions with
opposite charges attract and form (chemical) bonds. Small residual
electrostatic forces between molecules allow them to form
macroscopic structures such as crystals. Electrostatic interactions
explain pseudo-forces used in popular computer programs used to
model properties of atoms, molecules, and proteins. By beginning
with the basics and then diving deeper into the topic, this book
aims to familiarize the reader with electrostatic forces at the
atomic and molecular level.
While neutron halos were discovered 30 years ago, this is the first
book written on the subject of this exotic form of nuclei that
typically contain many more neutrons than stable isotopes of those
elements. It provides an introductory description of the halo and
outlines the discovery and evidence for its existence. It also
discusses different theoretical models of the halo's structure as
well as models and techniques in reaction theory that have allowed
us to study the halo. This is written at a level accessible to
graduate students starting a PhD in nuclear physics. Halo nuclei
are an exotic form of atomic nuclei that contain typically many
more neutrons than stable isotopes of those elements. To give you a
famous example, an atom of the element lithium has three electrons
orbiting a nucleus with three protons and, usually, either 3 or 4
neutrons. The difference in the number of neutrons gives us two
different isotopes of lithium, Li6 and Li7. But if you keep adding
neutrons to the nucleus you will eventually reach Li11, with still
3 protons (that means it's lithium) but with 8 neutrons. This
nucleus is so neutron-rich that the last two are very weakly bound
to the rest of the nucleus (a Li9 core). What happens is a quantum
mechanical effect: the two outer neutrons float around beyond the
rest of the nuclear core at a distance that is beyond the range of
the force that is holding them to the core. This is utterly
counterintuitive. It means the nucleus looks like a core plus
extended diffuse cloud of neutron probability: the halo. The author
of the book, Jim Al-Khalili, is a theoretician who published some
of the key papers on the structure of the halo in the mid and late
90s and was the first to determine its true size. This monograph is
based on review articles he has written on the mathematical models
used to determine the halo structure and the reactions used to
model that structure.
Monte Carlo methods have been very prominent in computer simulation
of various systems in physics, chemistry, biology, and materials
science. This book focuses on the discussion and path-integral
quantum Monte Carlo methods in many-body physics and provides a
concise but complete introduction to the Metropolis algorithm and
its applications in these two techniques. To explore the schemes in
clarity, several quantum many-body systems are analysed and studied
in detail. The book includes exercises to help digest the materials
covered. It can be used as a tutorial to learn the discussion and
path-integral Monte Carlo or a recipe for developing new research
in the reader's own area. Two complete Java programs, one for the
discussion Monte Carlo of 4^He clusters on a graphite surface and
the other for the path-integral Monte Carlo of cold atoms in a
potential trap, are ready for download and adoption.
Advances in Atomic, Molecular, and Optical Physics, Volume 71
provides a comprehensive compilation of recent developments in a
field that is in a state of rapid growth as new experimental and
theoretical techniques are used on many problems, both old and new.
Topics covered include related applied areas, such as atmospheric
science, astrophysics, surface physics, and laser physics, with
timely articles written by distinguished experts. Sample content
covered in this release includes Attosecond generation and
application from X-ray Free Electron Lasers.
The confocal microscope is appropriate for imaging cells or the
measurement of industrial artefacts. However, junior researchers
and instrument users sometimes misuse imaging concepts and
metrological characteristics, such as position resolution in
industrial metrology and scale resolution in bio-imaging. And,
metrological characteristics or influence factors in 3D measurement
such as height assessment error caused by 3D coupling effect are so
far not yet identified. In this book, the authors outline their
practices by the working experiences on standardization and system
design. This book assumes little previous knowledge of optics, but
rich experience in engineering of industrial measurements, in
particular with profile metrology or areal surface topography will
be very helpful to understand the theoretical concerns and value of
the technological advances. It should be useful for graduate
students or researchers as extended reading material, as well as
microscope users alongside their handbook.
Volume 3 of this three-part series presents more advanced topics
and applications of relativistic quantum field theory. The
application of quantum chromodynamics to high-energy particle
scattering is discussed with concrete examples for how to compute
QCD scattering cross sections. Experimental evidence for the
existence of quarks and gluons is then presented both within the
context of the naive quark model and beyond. Dr Strickland then
reviews our current understanding of the weak interaction, the
unified electroweak theory, and the Brout-Higgs-Englert mechanism
for the generation of gauge boson masses. The last two chapters
contain a self-contained introduction to finite temperature quantum
field theory with concrete examples focusing on the
high-temperature thermodynamics of scalar field theories, QED, and
QCD.
