Atomic Force Microscope Topography of Nickel-Affected MoS₂ Model Catalysts

Abstract

Photoionization of the I + ion in the energy range of the 4d giant resonance has been studied using our recently developed open-shell random phase approximation with exchange (RPAE) method. Photoionization cross sections for the I + 4d-f, p, 5s-p, 5p-s, d have been obtained for each term of the ground configuration. Calculations include all the intra-shell and inter-shell coupling among the 4d, 5s and 5p subshells. Our maximum cross section in the energy region of the I + 4d giant resonance, 23.6 Mb at 90.9 eV, is in excellent agreement with the recent measurement, 23(3) at 90 eV.
