Investigation of breakup fusion in 16O + 124Sn system and its correlation with various entrance channel parameters

Forward recoil range distribution of evaporation residues (ERs) populated through complete fusion (CF) and incomplete fusion (ICF) dynamics in [Formula: see text]O + [Formula: see text]Sn system have been measured. Different full and partial linear momentum transfer components have been observed. The results indicate the occurrence of ICF involving break-up of [Formula: see text]O into 4He + [Formula: see text]C and 8Be + 8Be. However, the present data shows that the ERs are populated through both CF and ICF. A systematic study was performed which shows that the ICF fraction rises exponentially with the established entrance channel parameters and their various combinations. Moreover, these present results clearly show that [Formula: see text] is able to explain the ICF dynamics more conclusively than combined parameter [Formula: see text] for the systems having spherical or slightly deformed target. Further, the dependence of ICF dynamics on target structure has also been studied through a new parameter [Formula: see text] of the target. The parameter [Formula: see text] is directly associated with the target structure and has been found more effective and sensitive than existing parameters to investigate the target structure effect on ICF dynamics. Thus, the present observations suggest that [Formula: see text] ratio of the target should also be considered as an important entrance channel parameter which strongly affects the ICF dynamics.
