“…The mass distribution of fission fragments produced in the 12 C+ 169 Tm reaction is obtained by plotting the experimentally measured cross sections as a function of mass number. It is found to be symmetric and can be fitted with one Gaussian function manifesting the formation of fission fragments from compound nuclear processes at E lab = 89.25, 83.22, and 77.18 MeV [9]. The centroid and width parameters obtained from the analysis of mass distribution are found to be 88.18 ± 0.22 and 20.83 ± 0.62, 89.76 ± 0.29 and 20.11 ± 0.63, 91.4 ± 0.5 and 18.80 ± 0.96 at E lab = 89.25, 83.22, and 77.18 MeV, respectively.…”

“…The variation of (σ 2 M ) at and below the barrier energies needs to be further investigated. In order to understand how distribution of fragments depends on the choice of entrance channel parameters, mass variance for different projectile-target combinition [9] is plotted as a function of mass asymmetry (µ = M T −M P M T +M P ) in Fig. 2 (b).…”

With an aim to study different aspects of heavy-ion induced reactions following the evolution of compound nucleus formed via complete and/or incomplete fusion, the production cross sections of evaporation residues and fission-like fragments were measured in 12 C+ 169 Tm reaction at E lab = 77.18, 83.22, and 89.25 MeV. The recoil-catcher activation technique followed by offline γ spectroscopy was employed to measure the cross sections. Herein, we present the production cross sections of 26 fission-like fragments identified in this work. An attempt has been made to study the isotopic yield distribution and the mass distribution of fission-like fragments to discern various reaction mechanisms. The mass distribution of fissionlike fragments was found to be symmetric and broad substantiating their formation from compound nuclear processes. The mass variances (σ 2 M) has been found to increase monotonically with excitation energy above the Coulomb barrier for deformed 169 Tm target, and with increase in mass asymmetry of the system.
