【 摘 要 】

Fragment emission mechanism has been studied for the composites24,25Mg at same excitation energy (∼54 MeV). The inclusive energy distributions of the emitted fragments (Li and Be isotopes) have been measured. It has been observed that the fragments were emitted from a fully energy relaxed composite. The measured yield ratios of the fragments for the two reactions were compared with the statistical model prediction of the same. It was found that unlike Li isotopes, statistical model calculation deviates substantially for the Be isotopes. The observed deviations were due to the boost in the yields whenever there was a known alpha cluster nucleus, either16O or18O, as the complementary fragment of the binary decay.
