Atomic And Nuclear Physics by Subrahmaniyam N.

The evolution of parallel processor supercomputers in recent years provides opportunities to investigate in detail many complex problems, in many branches of physics, which were considered to be intractable only a few years ago.

This volume collects papers presented at the international workshop "Hadron-Nuclear Physics 09" held at Osaka, November 16-19, 2009.

This book presents more than 300 exercises, with guided solutions, on topics that span both the experimental and the theoretical aspects of particle physics. The exercises are organized by subject, covering kinematics, interactions of particles with matter, particle detectors, hadrons and resonances, electroweak interactions and flavor physics, statistics and data analysis, and accelerators and beam dynamics.

presentation of the classical and quantum free electron theories and their successes and shortcomings (Chapter 23). In order to explain the large differences in the electrical properties of solids as well as the peculiar properties of semiconductors, the existence of allowed and forbidden energy bands is investigated (Chapter 24). In this chapter, we introduce the concepts of the electron effective mass and of holes. Intrinsic and doped semiconductors, their electron and hole densities, and their electrical properties are discussed in Chapter 25. It is now a rather simple matter for the student to understand the behavior and the characteristics of semiconductor devices: diodes, bipolar transistors, field effect transistors, etc. Semiconductor devices are the subject of Chapter 26. The text concludes with two chapters unique to this physics textbook. In Chapter 27, we show how diodes and transistors can be used to construct the logic circuits (gates) that constitute the fundamental building blocks of the computer. Chapter 28 is a layman'S introduction to some of the techniques used in the fabrication of integrated circuits. The laboratory experiments for the first semester are standard in any physics department, and thus we do not feel that is is necessary to include them in this book.

This book treats complex atoms in detail, beginning with the two-electron atom and moving to carbon without the need for additional equations. Discusses spontaneous emission from an atom or molecule in an excited state using time-dependent perturbation theory.
