## Intermediate Quantum MechanicsGraduate students in both theoretical and experimental physics will find this third edition of Intermediate Quantum Mechanics, refined and updated in 1986, indispensable. The first part of the book deals with the theory of atomic structure, while the second and third parts deal with the relativistic wave equations and introduction to field theory, making Intermediate Quantum Mechanics more complete than any other single-volume work on the subject. |

I've only read the chapters on the Klein-Gordon equation and the Dirac equation and its solutions. They're excellent! Bethe takes the time and the few words necessary to explain the details of each derivation instead of doing the usual, "It's clear". He also references the key historical papers on each subject area.

Page xxi - PREFACE TO THE FIRST EDITION This book is intended to serve as a text for a second course in quantum mechanics, for graduate students in both theoretical and experimental physics.

Page 152 - This phenomenon is a result of the spin-orbit coupling, caused by the interaction of the magnetic moment of the electron with the magnetic field which a moving electron experiences in an electric field.

Page xix - Over time, it was expected that these informal accounts would be replaced by more formal counterparts — textbooks or monographs — as the cutting-edge topics they treated gradually became integrated into the body of physics knowledge and reader interest dwindled. However, this has not proven to be the case for a number of the volumes in the series: Many works have remained in print on an on-demand basis, while others have such intrinsic value that the physics community has urged us to extend their...

Page xix - Physics series has, since 1961, made it possible for leading physicists to communicate in coherent fashion their views of recent developments in the most exciting and active fields of physics — without having to devote the time and energy required to prepare a formal review or monograph. Indeed, throughout its nearly fortyyear existence, the series has emphasized informality in both style and content, as well as pedagogical clarity. Over time, it was expected that these informal accounts would...

It will keep in print those volumes in Frontiers in Physics or its sister series, Lecture Notes and Supplements in Physics, that continue to provide a unique account of a topic of lasting interest. And through a sizable printing, these classics will be made available at a comparatively modest cost to the reader. These lecture notes by Giorgio Parisi, first published a decade ago, are by any definition a "classic...

Page 372 - Hence the angular momentum is no longer a constant of the motion. On the other hand, the existence of two linearly independent solutions corresponding to a given value of the energy indicates that an operator that commutes with the Hamiltonian must exist. We shall show that this operator is...
