Abstract
The quasirelativistic approach was used to derive transition data for the Rh-like W29+ tungsten ion. The quasirelativistic approach was developed specifically for the calculation of spectral parameters of highly charged ions. The relativistic effects were taken into account in the Breit–Pauli approximation. The configuration interaction method was applied to include electron correlation effects. The ground W29+ configuration 4p64d9 and two odd-parity configurations 4p54d10 and 4p64d84f were investigated. Different sets of configuration-interaction extensions were applied for assessment of calculation accuracy. The level energies, radiative lifetimes τ, and Landé g-factors were determined for levels of the excited configurations 4p54d10 and 4p64d84f and the ground configuration 4p64d9. The radiative transition wavelengths λ and emission transition probabilities A for the electric and magnetic transitions of high multipole order among the levels of these configurations were produced. The uncertainties of computed spectroscopic parameters were evaluated. Such a complete and inclusive data set for the levels of two excited configurations and their radiative properties in W29+ is reported for the first time.
