Angle resolved high resolution studies of the Xe 4d5/2 → 6p resonance

The Auger resonant Raman effect has been used as a method to eliminate the natural lifetime broadening in resonant Auger Spectra. The authors have coupled this method for the first time with high resolution from the ALS to study angular distributions and decay rates of the Xe 4d5/2 → 6p resonant Auger lines. The angular distribution parameters β of almost all possible final ionic 5p4(3P,D,S)6p states have been determined. The authors' data, which remove the discrepancy between previous lower-resolution experimental results, are compared to different theoretical results
