The disruption of massive stars, resulting from an explosion deep in their cores, is the most likely cause of Type II supernovae. Van Riper and Lattimer (1981) have studied the collapse of the core of a 15 solar masses star. At several times nuclear density the pressure is large enough to halt the implosion, and the homologous core 'bounces' and then rebounds slightly as it settles into hydrostatic equilibrium. A shock wave develops at the boundary between the stationary or expanding inner core and the infalling outer core. The current investigation is mainly concerned with the bounce and the propagation of the shock, continuing the evolution of the models described by Van Riper and Lattimer a few milliseconds further. It is found that the shock wave initially moves outward, but is weakened and 'fizzles' after it reaches densities where neutrinos, which are copiously produced by electron captures in the hot, dissociated shocked matter, can escape freely from behind the shock.
