Solid-State Effects on the Valence-Band4d-Photoionization Cross Sections at the Cooper Minimum

Abstract
Experimental evidence is presented for solid-state effects on the 4d photoionization around the Cooper minimum for a few transition metals: Ag, Pd, Mo, and Zr. The 4d parital cross section appears to be very sensitive to the dd interaction; thus, the antibonding d states have a more atomiclike cross section than the bonding d states.
