Many-body effects at the Si- L2,3 Auger lineshape: the case of Ca-silicides / M., Sancrotti; I., Abbati; L., Calliari; F., Marchetti; Bisi, Olmes; A., Iandelli; G. L., Olcese; A., Palenzona. - In: PHYSICAL REVIEW. B, CONDENSED MATTER. - ISSN 0163-1829. - STAMPA. - 37:(1988), pp. 4805-4808. [10.1103/PhysRevB.37.4803]
Abstract:
A joint experimental and theoretical analysis of the Si L2,3VV line shape of CaSi2 and Ca2Si is presented. While the pp-two-hole contribution to the Auger line shape of the two Ca silicides is well described by a one-particle picture, strong hole-hole repulsive effects (U∼3 eV) are present in the Auger process involving Si 3s states in Ca2Si. These correlation effects are consistently related to the quasiatomic nature of the Si 3s states in Ca2Si.
