It is pointed out that a nu(mu) or nu(tau) neutrino with a cosmologically significant mass (10-100 eV) are a small mixing with a light nu(e) would result in a matter-enhanced Mikheyev-Smirnov-Wolfenstien resonant transformation between these species in a region above the neutrino sphere but below the stalled shock during the reheating phase of a Type II supernova. The neutrino heating behind the shock is due to charged-current nu(e) and average nu(e) captures. Since the nu(mu) and nu(tau) have considerably higher average energies than do the nu(e), neutrino flavor mixing would result in higher effective nu(e) energies behind the shock and a concomitant increase in the heating rate. Numerical calculations suggest that this effect results in a 60 percent increase in the supernova explosion energy, possibly to solve the energy problem of delayed-mechanism supernova models.
