Research Abstract

A magneto-optical trap and a pulse dye laser for were developed for rubidium atoms to produce ultra cold Rydberg atoms. As a preparation experiment for quantum control of ultra cold Rydberg atoms, the spectra of several different nd states for cold Rb atoms at a long time delay after laser excitation to the Rydberg states. The results were discussed from the point of view of black body radiation effect and inelastic Rydberg-electron collision effect.
