    In the present work, the onset and strength of incomplete fusion were studied in terms of various entrance channel parameters. Excitation functions for individual evaporation residues were measured in the 12C+169Tm system at energies from 5 to 7.5AMeV, and analysed in the framework of the statistical model code PACE-IV to deduce the fraction of incomplete fusion. It was found that the probability of incomplete fusion increases with the incident energy as well as with the mass asymmetry of interacting partners for individual projectiles. Moreover, the critical value of the input angular momentum (lcrit) obtained from the experimental cross sections was compared with that calculated using the Wilczynski formula and a slight difference has been found. © 2018 Jagellonian University.

    Entrance channel effects on fission fragment mass distribution in 12 C+ 169 Tm system
    (Jagellonian University, 2019) Sood, Arshiya; Kumar, Pawan Santhosh Ashok; Sahoo, Rudra N.; Singh, Pushpendera P.; Yadav, Abhishek; Sharma, Vijay Raj; Sharma, Manoj Kumar; Aydın, Sezgin
    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 ? 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 fission-like fragments was found to be symmetric and broad substantiating their formation from compound nuclear processes. The mass variances (? M 2 ) 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. © 2019 Jagellonian University.
