ABSTRACT The article is mainly devoted to the calculation of energy loss and resulting spin asymmetry due to the processes ν𝑖 → ν𝑖e-e+ when electrons are generated in the main Landau level and positrons are generated in the first Landau level in the case of longitudinal and transverse polarization. This means that the contribution of positrons created at the first Landau level and whose spins are "right" polarized to the cooling of an ordinary neutron star due to the ν̃𝑖 → ν̃𝑖e-e+ processes is significantly greater than the contribution made by positrons created at the first Landau level and whose spins are "left" polarized. And in the case of a magnetic environment with B ~ 1014Qs arranged magnetic fields, a sufficiently large value is obtained for the asymmetry: A ≌ 97,5%. In this case, the magnetic environment with magnetic fields with magnetic induction B ~ 1014Qs cooling due to the ν̃𝑖 → ν̃𝑖e-e+ processes is dominated by the contribution of positrons created in the first Landau level and with "right" polarized spins. Keywords: asymmetry, magnetic field, positron, neutrino, electron. DOI:10.70784/azip.1.2024470 Received: 10.12.2024 Internet publishing: 23.12.2024 AUTHORS & AFFILIATIONS 1.
