    Entrance channel effect on incomplete fusion
    (Jagellonian University, 2018) Sahoo, Rudra N.; Kaushik, Malika; Sood, Arshiya; Kumar, Pawan Santhosh Ashok; Sharma, Vijay Raj; Yadav, Abhishek; Shuaib, Mohd; Aydın, Sezgin
    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.

    Insights into the low energy incomplete fusion
    (Elsevier B.V., 2019) Sahoo, Rudra N.; Kaushik, Malika; Kumar, Pawan S.Ashok; Sood, Arshiya; Sharma, Vijay Raj; Yadav, Abhishek; Singh, Pushpendera P.; Aydın, Sezgin
    In the present work, channel-by-channel excitation functions of different evaporation residues populated via complete and/or incomplete fusion in C12+169Tm system have been measured for an energy range Elab?53–90MeV, using recoil-catcher activation technique followed by off-line ?-spectroscopy. Experimentally measured excitation functions have been analysed in the framework of statistical model code PACE. To probe the effect of entrance-channel parameters on the onset and strength of incomplete fusion, relative contributions of complete and incomplete fusion have been deduced from the analysis of experimentally measured excitation functions. The percentage fraction of incomplete fusion deduced from the analysis of excitation functions has been studied in terms of incident energy, entrance-channel mass-asymmetry, ground state alpha-Q-value, neutron skin thickness of target nuclei, and nuclear potential parameters. It has been found that incomplete fusion start competing with complete fusion even at slightly above barrier energies where complete fusion is assumed to the sole contributor. The probability of incomplete fusion increases with incident energy, entrance channel mass-asymmetry, large negative ground state alpha-Q-value, neutron skin thickness, and nuclear potential parameters for individual projectiles.
