摘要：

A light sterile neutrino species has been introduced to explain simultaneously the solar and atmospheric neutrino puzzles and the results of the LSND experiment, while providing for a hot component of dark matter. Employing this scheme of neutrino masses and mixings, we show how matter-enhanced active-sterile (nu(mu,tau) reversible arrow nu(s)) neutrino transformation followed by active-active (nu(mu,tau)reversible arrow nu(e)) neutrino transformation can solve robustly the neutron deficit problem encountered by models of r-process nucleosynthesis associated with neutrino-heated supenova ejecta.
