To the problem of the contribution of spin-polarized protons to Baryshevsky–Luboshits effect

Abstract

Baryshevsky-Luboshits effect is possible not for spin polarized electrons only. A similar possible effect is predicted for spin polarized protons. The general structure of the formula for the angle of rotation of the plane of polarization of a photon moving among spin polarized protons depends on the difference of Compton scattering cross sections for the same and opposite spin directions of a photon and a proton. The contribution is obtained to such a formula depending on the integral of the difference of the corresponding cross sections. The final formula contains terms with double, triple and quadruple integrals. The problem is of interest for astrophysics because the possibility of spin polarization of protons is predicted for some types of stars (white dwarfs, Supernovae of type II), and if leads to the problem of the contribution of protons to Baryshevsky–Luboshits effect in comparison with spin polarized electrons.
