ONE-STEP AND 2-STEP PROCESSES IN THE LI-6(D,LI-6), (D,LI-7) AND (D,BE-7) REACTIONS AT E(D)=50MEV

The cross sections for the (d,Li-6), (d,Li-7) and (d,Be-7) reactions o n the Li-6 nuclei were measured at the deuteron energy of 50 MeV for t ransitions to the ground state of Li-6 and to the ground and first exc ited states of Li-7 and Be-7 nuclei. The experimental data were analyz ed with the coupled reaction channel model. It was found that both one - and two-step cluster transfers give substantial contributions to the cross sections. Reasonable agreement between measured and calculated cross sections was achieved. The asymmetry in the angular distribution s between the (d,Li-7) and (d,Be-7) reactions was observed experimenta lly. We discuss the effects that lead to the charge symmetry violation .
