Abstract

The angular distributions of deuterons for 7/sup 0/ < or = theta/sub c.m./ < or = 60/sup 0/ have been measured for 56.3 MeV neutrons incident on targets of /sup 6/Li and /sup 7/Li. Transitions corresponding to the pickup of 1p-shell and 1s-shell protons are strong with the latter exhibiting structure indicative of groups of excited states in /sup 5/He and /sup 6/He. In /sup 5/He these have excitation energies of 16.7, 18.5, and 20.5 MeV, and in /sup 6/He an average excitation energy of 15.6 MeV. The spectroscopic factors deduced from the measurements are in good agreement with theoretical values where the latter are available.
