摘要：
A new mechanism of supernova shock revival is proposed which involves the resonant spin-flavor precession of neutrinos with a transition magnetic moment in the magnetic field of the supernova. The mechanism can be operative id supernovae for transition magnetic moments as small as 10(-14)mu(B) provided the neutrino mass squared difference is in the range Delta m(2) similar to(3 eV)(2)-(600 eV)(2). it is shown that this mechanism can increase the neutrino-induced shock reheating energy by about 60%.
