Abstract

A study has been made of the influence of multiple-ionization satellites on the form of LII,III in emission spectra of elements of the beginning of period four in compounds. In order to simulate the influence of the environment on the intensity of the satellite radiation in KCl and Sc2O3, the calculation was carried out in KH6 and ScH6 clusters. A one-channel approximation of the one-center method was used to calculate the one-electron orbitals of the clusters. It was found that the polarization of the functions of valence electrons during the appearance of an additional vacancy in the 3p shell the almost-tenfold increase in the lifetime of the 2p−13p−1 configuration relative to the 2p−1 configuration leads to an appreciable influence of the multiple-ionization satellites on the LIII,III emission spectrum of potassium. In the case of scandium, the effect is slightly smaller because of the appearance of valent states located in the region of the central atom (which leads to a decrease in the lifetime of the 2p−13p−1 configuration), a decrease in the probability of emission of a 3p electron, and a reduction of the polarization of valent electrons upon the appearance of a 3p vacancy.
