Abstract

The angular distributions of the spin-orbit state resolved S [Formula Presented] photoelectrons of [Formula Presented] have been measured in the vicinity of the shape resonances. Relative partial photoionization cross sections of [Formula Presented] into the (S [Formula Presented] and (S [Formula Presented] states, and the asymmetry parameters of the S [Formula Presented] and S [Formula Presented] photoelectrons are presented. Enhancement of the photoionization cross section into the (S [Formula Presented] state at the (S [Formula Presented] [Formula Presented] resonance has been observed. The excitation photon energy dependence of the asymmetry parameter shows a broad dip at about the photon energies of the resonances. Continuum multiple-scattering calculation of the asymmetry parameters for the (S [Formula Presented] and (S [Formula Presented] states of [Formula Presented] reproduces this behavior.
