The crystal field splitting and g values in SrF 2 :Tm 2+ were calculated within the framework of the (TmF 8 ) 6− cluster using the Heitler‐London method. Two sorts of numerical Hartree‐Fock functions for Tm 2+ electrons were used in the calculations. It is shown, that a better agreement between the values calculated and observed may be obtained using more expanded radial functions of the Tm 2+ electrons.
