'Today a thorough understanding of atomic and molecular physics is surely a prerequisite for a career in astrophysics, especially now that the entire electromagnetic spectrum of many astronomical objects may be open to quantitative examination. Given the need for a sound understanding, the question becomes, how are students to develop a serious interest in atomic and molecular physics? This book by Mark Fox deserves consideration for an atomic-physics course taken by physics (and other) students in the second half of their undergraduate career … I welcome this book for its clear exposition of the basic ideas on atomic structure and spectra. … The health of spectroscopic astrophysics demands that young bright minds are brought into the field in every generation. Texts like that by Mark Fox have a crucial role to play in this context.' David L. Lambert, The Observatory

'Well-chosen worked examples are liberally sprinkled through all the chapters. This is an invaluable aid to the reader … The text is clear to read and understand, and only a basic understanding of quantum mechanics and electromagnetism is required … The harder mathematical concepts are hidden away in Appendices, so they are still available for the more intrepid reader, but do not spoil the flow of the main text … I would agree that the material is pitched at the second or third year of a UK undergraduate physics course, but it would also be useful for specialists in other fields starting out in the world of atomic physics.' Stephen H. Ashworth, Contemporary Physics

'This is a well-constructed book with a great many exercises at the end of each chapter. These exercises are of tremendous value, enabling students to solve a wide variety of problems in the subject. I would recommend this book for anyone who wanted a basic understanding of atomic physics.' Trevor Bailey, Mathematics Today
