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.
