Abstract

The energy distributions of the complex fragments (3≤Z≤11) emitted in the reaction F19(96 MeV) + C12 have been measured in the angular range 10°≤θlab≤60°. The lighter fragments (3≤Z≤6) have been found to be emitted predominantly due to the asymmetric fissionlike decay of the compound nucleus, whereas the heavier fragments (Z≥10) have been identified as evaporation residues. The shapes of the fragment energy distributions, as well as the total elemental yields for the lighter fragments (3≤Z≤6) have been explained fairly well by the asymmetric binary fission model. The binary fragment yields from the reaction F19(96 MeV) + C12 have been compared with those obtained in α(60 MeV) + Al27 and Li7(47 MeV) + Mg24 reactions, all producing the same composite P31 at same excitation energy. No significant entrance channel asymmetry dependence has been observed. © 1996 The American Physical Society.
