Experimental Signatures For Distinguishing Breakup Fusion And Transfer In Li-7+Ho-165
PHYSICAL REVIEW C(2005)
摘要
Reactions involving weakly bound nuclei of Li-7 show large yields of alpha particles that have their origin in elastic breakup, breakup followed by fusion, or triton transfer. The latter two processes, breakup fusion and transfer, have similar characteristics and produce the same residual fragments. We report here results of exclusive measurements of charged particles and characteristic gamma rays from the heavy residues in the Li-7+Ho-165 system at 42 MeV (E/V-b similar or equal to 1.6) to look for experimental signatures to differentiate between transfer and breakup fusion. Such a distinction is essential for a better theoretical understanding of both the fusion process and direct reactions involving weakly bound stable and unstable beams.
