Abstract
L3 X-ray absorption near edge peak often provides amount of empty d state of the X-ray absorbing atoms. Monovalent Ag compounds formally have a d10 state and it shows a small peak at the edge due to the s-d hybridization. Rocksalt structure of AgCl also gives the edge peaks though the local symmetry (Oh) of Ag does not allow the s-d hybridization. In this paper we have considered the origin based on the molecular orbital picture. We proposed the edge peak occurs owing to the s-d hybridization with the two-electron excitation created by the metal ligand covalency. [DOI: 10.1380/ejssnt.2012.609]
