Measurements of discrete nuclear reactions induced by a radioactiveLi8beam

Abstract
Energy- and angle-resolved nuclear reactions, primarily one-nucleon stripping, have been observed for targets of CD2, Be, and C, using a radioactive Li8 beam (T1/2=842 ms) at E=14.3 MeV. The (8Li,7Li) neutron transfer reaction populating discrete final states was identified and angular distributions were obtained. This direct-reaction channel has large cross sections (10100 mb/sr) due, in part, to the unique nuclear properties of Li8. Implications for astrophysical abundances of Li isotopes may be significant.
