Neutrino energy emission by beta processes in a mixture of nuclei of arbitrary electron and positron capture beta decay in the presence of a superstrong magnetic field is considered. The value of the interaction function for beta particles and nuclei in a quantizing magnetic field is estimated before calculating the effective cross sections for beta capture and decay. Energy emitted per unit time in beta capture by a stable nucleus with allowance for the number of quantum states in a magnetic field is determined, and the energy of the emitted neutrinos is determined for the case of beta capture by a radioactive nucleus. The differential probability of beta decay is calculated, and the total energy of neutrino-antineutrino emission for a unit volume per unit time is determined with allowance for the quantizing action. Results indicate that the influence of the Columb field on beta processes can be neglected, and that for the case of free nucleons, the energy of neutrino-antineutrino emission at densities greater than 1 million g/cu cm increases in the entire temperature range.
