[pdf] Problems and Solutions on Atomic, Nuclear and Particle Physics (Major American Universities PhD Qualifying Questions and Solutions) Yung-Kuo Lim

This is the best problem and solutions book in Atomic Physics I sow! It has a broad variety of detail solved problems, from those which are almost easy to those which are really hard. I use that one like main book in Atomic Physics to prepare myself for Ph.D. qualifier. I also highly recommend this book to all graduate students, as well as to those undergraduate who are willing to learn more than they can from ordinary undergraduate courses.
