Collision-Induced Dipole Transitions Associated with Rydberg States of Rubidium in Xenon

Abstract

For rubidium atom perturbed by xenon, absorption measurements have been made to observe collision-incuded dipole transitions 5 s - n s ( n =10 and 11), - n d (8≤ n ≤16) and - n q (7≤ n ≤15), where q stands for the manifold states of l ≥3. The n -dependence of the measured effective oscillator strengths is reproduced well by the approximate calculation using a simple model based on the interaction of a Rydberg electron with a xenon atom, although the calculation gives larger values than the experiment by a factor of about 4.
