Mass-asymmetry effects in heavy ion reactions: Complete fusion Vs incomplete fusion

Abstract

The excitation functions for 59Co(12C,pn) 69Ge, 59Co(12C,2pn)68Ga, 59Co(12C,p4n)68Ge, 59Co( 12C,αp4n)62Zn reactions for 12C+ 59Co projectile-target system have been measured for the first time. The recoil catcher technique followed by off-line γ-ray spectroscopy with HPGe detectors was used. The measured excitation functions are compared with the calculations based on the available tatistical model codes. The probability of incomplete fusion is found to increase with the projectile energy. Moreover, an attempt has been made to observe the impact of mass-asymmetry on incomplete fusion probability. The effect of α-break-up energy (Qα) on the ICF probability is also studied with the available data. © Owned by the authors, published by EDP Sciences, 2014.
