Resonances of the photoelectron spin-polarization parameters in the 5p autoionization range of xenon

Heckenkamp C, Schäfers F, Schönhense G, Heinzmann U. Resonances of the photoelectron spin-polarization parameters in the 5p autoionization range of xenon. Physical Review A: Atomic, Molecular and Optical Physics. 1985;32(2):1252-1255.The spin-polarization parameters for photoelectrons from xenon atoms have been measured in the wavelength range between 96 and 100 nm in an angle-resolving experiment using circularly polarized synchrotron radiation. Theoretical calculations (relativistic random-phase approximation and multichannel quantum defect theory) generally reproduce the wavelength dependence of the parameters, but there are some systematic deviations from the experimental data
