Abstract

Expressions have been obtained on the basis of S-matrix theory for the computation of electrical multipole transition probabilities in a relativistic approximation in a multielectron atom in first-order field perturbation theory. Also considered are corrections corresponding to simultaneously taking account of the external field and the interelectron interactions. Results of computing the wavelengths and probabilities of intercombinational transitions in multicharge ions between the configurations 1s 2p-1s2 for 4 ≤ Z ≤28 and 1s2 \(2s^n 1 2p^{n_2 } - 1s^2 2s^{n_1 \pm 1} 2 p^{n_2 \pm 1} \) for20 ≤ Z ≤ 30 are presented. The data obtained can be used to interpret soft x radiation originating in transitions observed in the solar corona and high-temperature plasma laboratories.
