Query: Energy level properties of 4p$^6$4d$^3$, 4p$^6$4d$^2$4f and 4p$^5$4d$^4$
  configurations of W$^{35+}$ ion   The ab initio quasirelativistic Hartree-Fock method developed specifically
for the calculation of spectroscopic parameters of heavy atoms and highly
charged ions was used to derive spectral data for the multicharged tungsten ion
W$^{35+}$. The configuration interaction method was applied to include the
electron-correlation effects. The relativistic effects were 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 $\mathrm{4p^64d^3}$, $\mathrm{4p^64d^24f}$
and $\mathrm{4p^54d^4}$ configurations of the W$^{35+}$ ion.
