Extended previous models to include nonzero invariants.

Enhanced understanding of neutrino interactions in external fields.

Abstract

Neutrino-photon interactions in the presence of an external homogeneous constant electromagnetic field are studied. The $\nu \nu \gamma $ amplitude is calculated in an electromagnetic field of the general type, when the two field invariants are nonzero.
