Abstract

Including nucleon-nucleon correlations due to both Fermi statistics and nuclear forces, we have developed a general formalism for calculating the charged-current neutrino-nucleon absorption rates in nuclear matter. We find that at one-half the nuclear density many-body effects alone suppress the rates by a factor of 2 and that the suppression factors increase to [Formula Presented] at [Formula Presented] The associated increase in the neutrino-matter mean free paths parallels what we have found for neutral-current interactions and may open up interesting possibilities in the context of the delayed supernova mechanism and protoneutron star cooling.
