Abstract

Particle-γ coincidences from 75 MeV 6Li bombardment of 197Au reflect the transfer of a beam-velocity α or d fragment, initiating a (particle, xnγ) reaction. This reaction channel appears to account for approximately 13% of the beam-velocity particle production.

    The exclusive breakup for 6,7Li + 65Cu contributes less than 10% and compound nucleus evaporation less than 30% towards the observed large alpha-singles cross-section. The origin of the large alpha yield in 6Li( 7Li) induced reactions seems to be mainly due to deuteron(triton) capture/deuteron(triton) transfer as discussed in [7–11]. In a recent study with 6,7Li on a medium mass target, 64Zn, very large cross-sections for the break up (where both the fragments survive) have been indirectly inferred by subtracting the complete and incomplete fusion cross-sections from the reaction cross-section [38].
