Scientific paper

The detected neutrino pulse of finite width correlated with the optical discovery of SN 1987A in the LMC allows the determination of the neutrino rest mass. Taking into account possible uncertainties in both the original width of the emitted neutrino pulse and the expected neutrino energy spectrum from type II supernovae, an electron neutrino rest mass of 11-23 eV/c sq is derived, in agreement with the recent limit obtained from decay experiments.
