Fission dynamics and related aspects of ¹⁸¹Re∗ nucleus formed in ¹²C induced reaction

The fission of the ¹⁸¹Re∗ nucleus formed via the ¹²C +¹⁶⁹Tm reaction is studied at E_Lab= 77–89 MeV within the dynamical cluster model (DCM) for the choices of spherical as well as deformed fragments originated in binary decay channels of the of collective clusterization approach. The mass distribution of the compound nucleus ¹⁸¹Re∗ is analyzed for both choices and compared with the available data, and consequently the probable fission fragments are identified. The barrier height, barrier modification, and barrier penetrability of the fission fragments are investigated. The total fission cross-sections are calculated for spherical as well as deformed choices of fragmentation, and they are in nice agreement with experimental data. In addition, the fission emission times and the decay widths of the fission fragments are predicted for comparison with future experiments. Finally, the preformation behavior of spontaneous and induced fission paths are compared to give a better insight of the decay mechanism of ¹⁸¹Re nucleus. (author)
