Cross sections have been measured up to 35 MeV excitation for the 76 Se͑n,p͒ 76 As reaction at five laboratory angles between 0°and 15°. The incident neutron energy was 198 MeV. The distribution of Gamow-Teller ͑GT͒ strength at excitation energies less than 10 MeV was deduced by carrying out a multipole decomposition of the data. The GT strength below 6 MeV excitation was found to be less than 0.9 units, in qualitative agreement with a quasiparticle random-phase approximation calculation. The present results have been compared with data from the 76 Ge͑p,n͒ 76 As reaction to obtain an estimate of a lower limit for the lifetime of 76 Ge for  decay. The estimate is in qualitative agreement with the measured lifetime.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
