Quasirelativistic calculation of 4s${}^2$4p${}^5$, 4s${}^2$4p${}^4$4d and 4s4p${}^6$ configuration spectroscopic parameters for the W${}^{39+}$ ion

Abstract

The ab initio quasirelativistic Hartree-Fock method developed specifically for the calculation of spectral parameters of heavy atoms and highly charged ions is used to derive spectral data for the 4s${}^2$4p${}^5$, 4s${}^2$4p${}^4$4d and 4s4p${}^6$ configurations of the multicharged tungsten ion W${}^{39+}$. The relativistic effects are taken into account in the Breit-Pauli approximation for the quasirelativistic Hartree-Fock radial orbitals. The configuration interaction method is applied to include the electron correlation effects. Produced data are compared with existing experimental measurements and theoretical calculations.
