Abstract

FKα X-ray satellite spectra of NaF and KF induced by photon impact were observed. The intensity of a K1L1 satellite peak relative to a K1L0 diagram line of KF was much reduced compared to that of NaF. The reduction in the relative intensity of the K1L1 satellite peak of KF has been explained qualitatively by the delocalization of the F2p-1 hole through molecular orbitals in the ionized or K1L1 state. However, a degree of the reduction in the K1L1 satellite peak intensity was estimated here quantitatively from calculations of X-ray emission rates using the numerical basis SCC-DV-Xα method in the ionized or hole states. The calculated results indicate that the formation of molecular orbitals in the K1L1 state of KF is not responsible for the reduction in X-ray emission rate for the K1L1 satellite.
