Abstract

Atomic properties of Cd-like W26+, In-like W25+, and Sn-like W24+ ions are evaluated by using a relativistic CI + all-order approach that combines configuration-interaction and the coupled-cluster methods. The energies, transition rates, and lifetimes of low-lying levels are calculated and compared with available theoretical and experimental values. The magnetic-dipole transition rates are calculated to determine the branching ratios and lifetimes for the 4f(3) states inW(25+) and for the 4f(4) states in W24+ ions. Excellent agreement of the CI + all-order values provided a benchmark test of this method for the 4f(n) configurations validating the recommended values of tungsten ion properties calculated in this work.
