- Abstract
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 12C+169Tm reaction at Elab = 77:18, 83.22, and 89.25 MeV. The recoil-catcher activation technique followed by offline 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 (σ²M) has been found to increase monotonically with excitation energy above the Coulomb barrier for deformed 169Tm target, and with increase in mass asymmetry of the system.
