ON THE THEORY OF SPIN-WAVES IN NONFERROMA GNETIC METALS WITH QUASI-LOCAL STATES OF ELECTRONS

New branches of the spin wave spectrum of non-ferromagnetic metals wit h quasi-local electron states have been found. The spectrum and decrem ent or waves propagating in an arbitrary direction relative to the mag netic field have been obtained. The differential cross-section of neut ron magnetic scattering by new spin waves and single-particle excitati ons of electrons localized at impurities has been calculated for any s cattering angle. There are asymmetric peaks outside the Stoner continu a in the energy spectrum a scattered neutrons due to scattering by sin gle-particle excitations. Scattering by spin waves results in a series of Lorentz satellites which are symmetric relative to the undisplaced line.
