Abstract

The shift and broadening of Doppler-free, two-photon transitions to Rydberg states of alkali atoms are analyzed for the case of Rb in the framework of a molecular approach to collisions of ground state and Rydberg atoms. The overall features of the observed spectra are determined by the electrostatic interactions between the two atoms and are calculated using the impact theory of spectral line-shapes. The superimposed oscillations in the widths and shifts as functions of the Rydberg quantum number can be understood in terms of resonance electron-ground state atom scattering. The corresponding contributions to the spectra are determined by the energy and lifetime of a ³P autoionizing state of the negative alakali ion.
