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.
