摘要：
We analyze the influence of neutrino helicity conversion, nu (L) -> nu (R), on the neutrino flux from a supernova attributable to the interaction of the Dirac neutrino magnetic moment with a magnetic field.We show that if the neutrino has a magnetic moment in the interval 10(-13)A mu(B) < A mu(nu) < 10(-12)A mu(B) and provided that a magnetic field of similar to 10(13)-10(14) G exists in the supernova envelope, a peculiar kind of time evolution of the neutrino signal from the supernova attributable to the resonance transition nu (L) -> nu (R) in the magnetic field of the envelope can appear.
