After the development of the tunable laser, experimental studies in Rydberg states of atoms and molecules grew at a remarkable rate. Fundamental questions were

As a consequence of new experimental techniques in optical and collision physics, such as multiphoton excitation and VUV radiation generation, quantum defect th

An introduction to the physics of highly excited, easily perturbed or interacting atoms. Covers Rydberg states, quantum defect theory, atomic f-values, centrifu
