An investigation of the reaction 12C(p, 6Li)7Be at 36 to 57 MeV

Abstract Differential cross sections for the reaction 12 C(p, 6 Li) 7 Be (g.s. + 0.431 MeV) have been measured at incident proton energies of 36.0, 40.7, 45.0, 50.0 and 56.8 MeV. Angular distributions are presented for the c.m. angles generally between 20° and 160°. At the lowest energy differential cross sections are as large as 200 μb/sr. Excitation functions have been taken at energies from 36 to 43 MeV at the c.m. angles 37°, 67° and 90°. The data have been analyzed using zero-range and finite-range DWBA theories assuming the pick-up of 5 He and 6 Li clusters as the dominant reaction mechanisms.
