Atomic Physics

Merger of accelerator technology and radiofrequency spectroscopy to make a fast atomic beam for precision fine and hyperfine spectroscopy of atomic hydrogen. The use of a fast atomic beam permits spectroscopy and collisional studies to be performed on short-lived excited states under well-defined conditions largely free from extraneous fields. Probing The Atom

Theoretical description of the interaction of atoms with radiofrequency and optical fields. The theory permits the prediction of spectroscopic lineshapes from which detailed information can be extracted concerning atomic structure and interactions. Probing The Atom

General theory and experimental demonstration of laser-induced quantum interference in Rydberg atoms. The theory predicted novel nonlinear effects as well as quantum beat signals of atoms subjected to external static fields. More Than One Mystery

Investigation of the properties of exotic atoms, i.e. atoms in which an unstable particle replaces one or more bound electrons. In one such study the lifetime of the dimuon atom, prototype of an entirely new class of hitherto unexamined atomic species, was investigated for the first time. And Yet It Moves
