STIMULATED SCATTERING OF NEUTRINOS BY ELECTRON-CYCLOTRON-HARMONIC ANDCONVECTION MODES IN MAGNETOPLASMAS

A description of the nonlinear coupling between intense neutrino fluxe s and electro static electron-cyclotron-harmonic and convection modes in a nonuniform magnetoplasma is presented. It is found that the elect ron waves can be parametrically excited on account of the free energy of the coherent neutrino fluxes. The growth rates of the corresponding three-wave decay and modulational interactions are obtained. The nont hermally excited electrostatic plasma waves are associated with turbul ent collision processes, which can be responsible for the anomalous ab sorption of the neutrino energy in supernova explosions.
