Abstract
The observation1,2of neutrinos from the LMC supernova makes possible direct tests of the theory of supernova explosions and of properties of weakly interacting particles. Here we describe a combined analysis of the angular and energy distributions of the events observed in the Kamiokande and the 1MB detectors which determines the effective temperatures and fluxes of neutrinos and anti-neutrinos* produced by the explosion. Our main result is that a simple model is consistent with the available data and in reasonable agreement with conventional models of supernova explosions. The parameters of the model are: a single temperature, T, of 4.1+1.0â0.4 MeV, a flux of electron anti-neutrinos of (O.5-0.35+0.2)Ã1010cmâ2 [total energy in vÌe = (3.0+1.7â1.4 Ã 1052 erg)], and a poorly determined flux of 'scattered' (see below) neutrinos = (0.2â5)Ã 1010 cmâ2. Several statistical tests were used to determine the acceptable range of these parameters. We have also set limits on possible high-temperature fluxes of neutrinos or anti-neutrinos that might result from matter oscillations3,4
