Beta decay rates for S-process studies

The rates for a variety of beta decay processes have been determined as a function of temperature for nuclei which can participate in the s-process production of heavy elements, occurring in the presence of the 22Ne(α,n)25Mg neutron source operating in the convective helium shells of thermally pulsing stars. Specifically: calculated half-lives are presented for electron emission, positron emission, and electron capture over the temperature range 108-109 K. (orig.)
