Abstract
A coherent superposition of Rydberg states leads to a radially localized wave packet. This wave packet oscillates between the turning points of the classical Kepler orbit. The energy spacings between the Rydberg states determines the oscillation time. The differences in the spacings cause the effects of dispersion and revival of the wave packet. Photoionization is a sensitive probe to the amount of wave function near the core, because in a Coulomb potential ionization takes place only near the atomic core. In the experiment, a wave packet is created by coherent excitation of Rydberg states of Rb with a short laser pulse, and detected by photoionization with a delayed probe pulse. In this way two returns of the wave packet are observed.
