Abstract
Xenon 5p subshell photoionization has been studied in the vicinity of the Xe 4d shape resonance by angle and spin resolved photoelectron spectroscopy. Dipole matrix elements and relative phase shifts derived from these experimental data are compared with calculations with regard to the strength of interchannel and relativistic interactions. The comparison shows strong influence of interchannel interactions on the transition-matrix elements, particularly on the phase shift in the vicinity of the 4d shape resonance, but gives little evidence for relativistic interactions of comparable strength.
