Photoassociation of $^{85}$Rb Atoms in $0_{u}^{+}$ States Near the 5S+5P Atomic Limits

ORAL

Abstract

Analysis of photoassociation data on $^{85}$Rb atoms in a MOT (U. Conn.) or FORT (U. Texas) into $0_{u}^{+}$ states below the 5S+5P$_{1/2}$ (U. Conn.) and 5P$_{3/2}$ (U. Texas) limits reveals perturbations between the manifolds of states dissoociating to these two limits. These perturbation effects are exchibited most clearly as peaks in values of $B(v)$ vs. $v$ below the 5P$_{1/2}$ limit where intermixings with levels associated with the 5P$_{3/2}$ limit are maximal. From precision experimental data, we have fit long range and medium long range potentials and R-dependent spin-orbit functions. We will comment on deviations of observed energies from well known near-dissociation-limit expansion formulae.
