Abstract
The ab initio quasirelativistic approach developed specifically for the calculation of spectral parameters of highly charged ions has been used to determine transition data for the Tc-like tungsten ion W31+. This is the final paper of our studies examining spectroscopic properties of the tungsten ions with open 4d shell in the ground state. The configuration interaction method has been utilized to include electron correlation effects. The relativistic effects have been taken into account in the Breit–Pauli approximation. Level energies, their radiative lifetimes τ, and Landé g-factors have been determined for the ground configuration 4p64d7 and two excited configurations, 4p54d8 and 4p64d64f. The radiative transition wavelengths λ and emission transition probabilities A for the electric dipole, electric quadrupole, electric octupole, magnetic dipole, and magnetic quadrupole transitions among the fine-structure levels of these configurations have been computed and analyzed. The uncertainties of produced spectroscopic parameters have been evaluated.
