Abstract

The refined set of values of the effective nuclear charge (\( \bar Z_{ef} \)) and the set of one-electron spin-orbital constants (ξ3dteor) are obtained for ions of transition metals with the help of a semiempirical method of calculation of the spectrum of free ions with allowance for the spin-orbital interaction. The effective nuclear charge, which is a variable theoretical parameter, was determined from a comparison of theoretically calculated ion absorption spectra with experimental ones. The form of the potential for the calculation of the spin-orbital constant was chosen such that the calculated value ξ3dteor would coincide with the experimental one ξ3dexp. The calculated set of values \( \bar Z_{ef} \), ξ3dteor} can be used in semiempirical calculations of energy levels of 3d ions (ions with an incomplete 3d shell).
