Abstract
FKα X-ray satellite spectra of NaF and KF induced by photon impact were observed. The intensity of a K 1L 1 satellite peak relative to a K 1L 0 diagram line of KF was much reduced compared to that of NaF. The reduction in the relative intensity of the K 1L 1 satellite peak of KF has been explained qualitatively by the delocalization of the F2p −1 hole through molecular orbitals in the ionized or K 1L 1 state. However, a degree of the reduction in the K 1L 1 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 K 1L 1 state of KF is not responsible for the reduction in X-ray emission rate for the K 1L 1 satellite.
