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 transition data for multicharged tungsten ion. The configuration interaction method is applied to include electron correlation effects. The relativistic effects are taken into account in the Breit-Pauli approximation for quasirelativistic Hartree-Fock radial orbitals. The energy level spectra, radiative lifetimes $\tau$, Lande $g$-factors are calculated for the $\mathrm{4p^64d^2}$, $\mathrm{4p^64d4f}$ and $\mathrm{4p^54d^3}$ configurations of W$^{36+}$ ion. The transition wavelengths $\lambda$, spontaneous transition probabilities $A$, oscillator strengths $gf$ and line strengths $S$ for the electric dipole, electric quadrupole, electric octupole and magnetic dipole transitions among the levels of these configurations are tabulated.
