EXCLUSION PRINCIPLE INHIBITION OF BETA DECAY IN STELLAR INTERIORS
Journal Article
·
· Astrophysical Journal (U.S.)
Beta decay in a high-density electron gas is investigated. It is shown that the exclusion principle can play an important role in determining the decay rate. Tables describing allowed, first-forbidden nonunique, and firstforbidden unique decays are presented; these tables give the dependence of the beta-decay rate on the local temperature, electron density, and beta-decay energy. If the Fermi energy of the free electrons exceeds the beta-decay energy, the decay rate is strongly inhibited; the amount of inhibition decreases with increasing temperature. The relativistic dependence of the degeneracy parameter on temperature and electron density is also tabulated. (auth)
