AUGER RESONANT RAMAN-SPECTROSCOPY USED TO STUDY THE ANGULAR-DISTRIBUTIONS OF THE XE 4D(5 2)-]6P DECAY SPECTRUM/

The Auger resonant Raman effect can be used as a method to eliminate n atural lifetime broadening in resonant Auger spectra. We have coupled this method with high-resolution photons from the Advanced Light Sourc e to study angular distributions and decay rates of the Xe4d(5/2)-->6p resonant Auger lines. The angular distribution parameters beta of alm ost all possible final ionic 5p(4)(P-3,D-1,S-1)6p states have been det ermined. Our data, which remove the discrepancy between previous lower -resolution experimental results, are compared to different theoretica l results.
