摘要：Detailed knowledge of the Gamow-Teller strength distribution in medium-heavy nuclei is important for accurately estimating weak transition rates in thermonuclear and core-collapse supernovae. Charge-exchange reactions are an excellent tool to provide empirical information about Gamow-Teller strengths. A secondary, 115 MeV/nucleon triton beam has been developed at NSCL for use in (t,3He) charge-exchange reaction studies. Work is ongoing to extract Gamow- Teller strength distributions, particularly in p f -shell nuclei. We briefly overview the procedure with the 64Zn(t,3He)64Cu reaction as an example.
