For rubidium atom perturbed by xenon, absorption measurements have been made to observe collision-incuded dipole transitions 5s−ns (n=10 and 11), −nd (8≤n≤16) and −nq (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.
