เนื้อหาย่อ : In this new edition the author has sought, of course, to bring the material of the first edition up to date. There are a number of other changes. A chapter on the elements of wave mechanics has been added, and there has been some rearrangement of the remaining chapters, both as to order and as to scope. Some ma- terial of marginal interest has been dropped to avoid increasing the length of the book. A few selected derivations have been added in appendices, and references to others are made throughout the text. Most of these changes originated in the suggestions of users and reviewers, to whom the author is grateful. It is hoped that, if the appendices and much of the material in small type are omitted, the remainder of the book will be suitable for an introductory undergraduate course. Some exposure to atomic physics at the descriptive level is assumed. As in the frst edition "'nuclear physics" has been arbitrarily defined in a rather broad way to encompass fundamental particle physics, cosmic rays, molecular beams, and other topics that could well have been excluded.
