STIMULATED SCATTERING OF NEUTRINOS BY NEUTRONS

Stimulated scattering of the intense electron-neutrino burst in a back ground of neutrons is investigated. We derive the linear growth rates for several regimes of interest. It is shown that this process is form ally equivalent to the usual Stimulated Brillouin Scattering found in laser coupling to ion acoustic oscillations. The influence of this ins tability in the neutrino-sphere and the consequences for the supernova e dynamics are also discussed.
