Fragment emission studies of the 16O+12C reaction

The inclusive energy distributions of the fragments (3 <= Z <= 5) emitted in the reaction O-16+C-12 have been measured in the angular range 9(degrees) to 29(degrees), at the energies 117, 125, 145, and 160 MeV, respectively. The centroids of the fragments energy distributions follow Viola systematics, which suggest that the fragments are emitted from a fully energy relaxed composite-as expected for both FF and orbiting processes. The center of mass angular distributions of the fragments B, Be, and Li obtained at all the bombarding energies follow 1/sin theta(c.m.) like variation-which further corroborates the conjecture of emission from fully equilibrated composite. The average < Q > values for the fragments B, Be, and Li are found to be independent of the center of mass emission angles, which further suggest that at all angles, the fragments are emitted from completely equilibrated source at all incident energies considered here. The yields of the fragments Li and Be are in agreement with statistical-model predictions. The enhanced yields of entrance channel fragment B indicate the survival of orbiting-like process in O-16+C-12 system at these energies.
