## [8.05] Light Element Nucleosynthesis

S. Vahidinia (UCB/LBNL/UCSD), G. Fuller (UCSD)

The weak interaction rates of nuclei may be important for calculating the dynamics and nucleosynthesis yields of many astrophysical environments. The lepton (electron, positron, neutrino, antineutrino) capture rates and beta decay and positron decay rates for heavy elements (mass number A=21-60) have been calculated as functions of temperature and density in previous work. Here we extend a similar systematic calculation of these rates to the the light nuclei. We estimate lepton capture and decay rates for nuclear mass numbers A=1-20 on a grid of temperatures and densities relevant for nucleosynthesis environments in stars and in the early universe.
