Taking into consideration the third order corrections of perturbation theory for electron-ionic pseudopotential, the calculation of the effective interionic interaction potentials in 3d-transition metals was carried out. For more full consideration of the model potential nonlocality in determination of its form-factors the procedure of the angular coordinates averaging was used. The analysis of the calculated potentials shows that the consideration of the third order corrections for model potential results in the increasing of the first minimum depth and decreasing of the equilibrium distance between ions.Comments: Figs. 4, Refs. 9, Tabs. 0.
