Role of Compound Nuclei and Deep-Inelastic Scattering in Complex Fragment Production at Intermediate Energies

摘要

The dependence of complex fragment production on the asymmetry of the entrance channel has been investigated with the 18A MeV (139)La + (12)C, (27)Al, (64)Ni reactions. Invariant cross section plots show a very simple pattern for the two lighter targets and a more complex one for the heavier sup 64 Ni target. The observed complex fragments are shown to result from quasi-elastic/deep-inelastic reactions and from compound nuclei formed in complete/incomplete fusion processes. 9 refs., 10 figs.
