Abstract The effect of electron‐static‐lattice and electron‐phonon interactions on the spin‐paramagnetism of metals is studied with a Hellmantype pseudopotential as the electron‐ion interaction potential. Numerical calculations show that the electron–static‐lattice interaction produces an enhancement of about 10% in the spin‐susceptibility of sodium. Further it is found that the electron‐phonon contribution to the spin‐susceptibility is of the order of . This confirms the result of Migdal, and Quinn and Ferrell that the spin‐susceptibility of an electron gas in a metal is unaffected by the electron‐phonon interactions to order , by means of a straightforward calculation.
