[en] Investigation into electron density oscillations around impurities in diluted solid solutions on the base of α-Fe is conducted. Using the experimental shifts of a superfine field on Fe atoms closest to impurity, phase shifts η_l^F of scattered partial l-order waves and k_F wave vector modulus of conductivity electrons on the Fermi surface are determined. The calculated values of phase shifts η_l^F and wave vector k_F allow one to calculate the residual electric resistance of Fe-Mn, Fe-Co and Fe-Ni solid solutions, which is in a good agreement with the experimental value. Parameters of electron density oscillations around Mn, Co and Ni impurities in diluted solid α-Fe-base solutions are determined
