Method of exact solutions in investigating the electromagnetic field influence on different quantum processes

Using the method of exact solutions of equations for the wave functions of particles, the following problems are studied in the presence of electromagnetic fields: 1)the polarization effects in the neutrino emission by an electron and e+e--pair annihilation into spinless bosons in magnetic field, 2)the effects of proton pure recoil in the β-decay of a neutron in a magnetic field, 3)the contributions of bosons of different types and composite Z,W and H bosons to the anomalous magnetic moment of a charged lepton moving in a magnetic field, 4)the stimulated emission and absorption of an electron in the electromagnetic field of Redmond configuration, 5)the theorem of equivalence of expressions for the probabilities of the processes e→e+ν+ν and e→e+Z in constant fields. 33 refs
