Abstract

Energy spectra of light charged particles emitted in the reaction have been studied and compared with statistical model calculation. Unlike ¹⁶O + ¹²C where a large deformation was observed in ²⁸Si^*, the energy spectra of -particles were well explained by the statistical model calculation with standard “deformability parameters” obtained using the rotating liquid drop model. It seems that the -clustering in the entrance channel causes extra deformation in ²⁸Si^* in the case of ¹⁶O + ¹²C, but the reanalysis of other published data shows that there are several cases where extra deformation was observed for composites produced via non--cluster entrance channels also. An empirical relation was found between mass-asymmetry in the entrance channel and deformation, which indicates that along with -clustering, mass-asymmetry may also affect the emission of a light charged particle.
