High-resolution experimental determination of the angular distribution and spin polarization of xenon 7d' and 9s' photoelectrons and comparison with theoretical results

Using narrowband tunable linearly or circularly polarized VUV radiation an examination of the dynamical parameters describing the autoionization process of atomic xenon was performed. With a resolving power of ~10⁵ in the excitation step a fully resolved determination of the position, magnitude and shape of the angular distribution and integral spin-polarization resonances was possible for the low Rydberg orders n=7 and n=9 of the d and s series, respectively. Comparisons are drawn between the experimental data and some theoretical calculations published in recent years.
