Massive neutrino generation by alternating fields with account for mixing and radiation effects

Probabilities are obtained for massive neutrino generations by an electromagnetic alternating field F → νiν-barjγ, FB → νiν-barj. The processes are conditioned by the contribution of four-particle vertices in the one-loop approximation with account for mixing. In the case of the vacuum neutrino synchrotron radiation is carried out a comparative analysis of values, considered in the paper and early discussed ones for the generation mechanisms F → νiν-barj. 7 refs
