Scattering and absorption of slow particles by a black hole

The process of scattering and absorption of low-relativistic electrons and scalar particles in Herr-Newman fields with the radius of events horizon less than the particle wave length are considered. Particle absorption by the events horizon causes polarization phenomena approximately rsub(g)/lambda at electron scattering. Corrections of the same order to differential scattering cross sections as well as expressions for total absorption cross sections are obtained. General formulas are applied for considering analogous processes with neutrino participation
