Atomic physics is a pioneering discipline at the forefront of theoretical physics. Thus, the 1997 Nobel Prize in Physics was awarded for the first successful preparation of Bose-Einstein condensates of atomic gases.This new edition of Theoretical Atomic Physics takes into account recent developments such as semiclassical theory, periodic orbit theory, scaling properties for atoms in external fields, threshold behaviour of ionization cross sections, and classical and quantum dynamics of two-electron atoms.Moreover, the student finds 48 problems with complete solutions which makes this course the most thorough introduction to the field available.
