Continuing the work of [1], the pseudopotential method is used to calculate the electron band spectra of the K3Sb crystal with a cubic symmetry group, for various parameters of the local, nonlocal, and spin-orbital terms of the pseudopotential. The theoretical dependences of the imaginary component of the dielectricpermittivity function calculated from these spectra are compared with one another and with the experimental dependence. The spin-orbital splitting of the valence band vertex of crystals of type A 2 I BISb is estimated.
