Alpha-Clustering in 75 MeV sup 16 O+ sup 40 Ca as a Collective Mass Fragmentation Process

摘要

The observed alpha -cluster structure in the mass yield distribution of 75 MeV sup 16 O+ sup 40 Ca reaction is shown to be a collective mass transfer. This is given as a dynamical mass fragmentation process in the fusion-fusion of the compound nucleus sup 56 Ni. The experimental data is found to suggest the use of oscillating adiabatic cranking mass parameters. The coupling effect of relative motion to the mass asymmetry co-ordinate is also studied, which is found to be negligibly small. (Atomindex citation 17:018466)
