Study of xenon 4d, 5p, and 5s photoionization in the shape-resonance region using spin-resolved electron spectroscopy
Abstract
Photoionization of Xe atoms is investigated close to the maximum of the 4d shape resonance by means of spin-resolved photoelectron spectroscopy. Using circularly and linearly polarized synchrotron radiation of 93.8-eV energy, we investigate the photoionization processes of the 5p, 5s, and 4d shells. By combination of earlier data for the partial and differential cross sections with our measurements, we are able to perform a complete characterization of the Xe 4d photoionization process, i.e., we can determine all the relativistic dipole matrix elements. Comparison with different theoretical calculations shows the importance of relaxation effects at this photon energy.
