摘要

Exploration of reaction dynamics of the weakly bound heavy-ion interaction with an intermediate or heavy mass target in the low energy range has been a subject of interest over the past decades; however, different modes of fusion such as breakup fusion, incomplete fusion, and transfer phenomena observed experimentally are not yet fully understood. Experimental studies are therefore essential to address the problem. In this article, we report a new set of cross-section data of the residues produced in the weakly bound Li-7 induced reaction on Ta-nat within the 27-45 MeV energy range. Along with the major yield of Os183g+m, production of Hf-180m and Ta-183 are also observed up to similar to 35 MeV, which is possibly an indication of the incomplete fusion mechanism or breakup-transfer phenomena. The trend of the isomeric cross-section ratio of Os-183 indicates the role of angular momentum and spin distribution besides the excitation energy, and is interpreted by theory. The optimized production parameters and yields of Os-183g,Os-m are assessed.
