Radiative Constants in the W VII Ion Spectrum

Abstract

The probabilities of the 4 f 135p66p + 4 f 145p56p – 4 f 136s, 4 f 137s radiative transitions and the lifetimes of the 4 f 137s levels in the spectrum of the erbium-like W VII ion are calculated in the electric dipole approximation by the semiempirical intermediate coupling method using experimental energy levels known from the literature. The radial integrals necessary for calculating the absolute transition probabilities are obtained in the form of length with the Hartree–Fock functions.
