NONLINEAR GENERATION OF RADIATION BY INTENSE NEUTRINO FLUXES IN DENSEMAGNETIZED PLASMAS

It is shown that intense neutrino fluxes can nonlinearly generate elli ptically polarized electromagnetic waves in ionized super-dense gases immersed in an external magnetic field. For this purpose, dispersion r elations for obliquely (perpendicularly) propagating (with respect to the direction of the ambient magnetic field lines) helicons (extraordi nary modes) influenced by the neutrino ponderomotive force are derived , The growth rates of the decay interactions are presented, These proc esses may contribute to the conservation of neutrino spins in supernov a explosions.
