Influence of projectile breakup on the 16 O + 115 in reaction at energies ≈ 4-7 MeV/nucleon

To study the influence of breakup on fusion of 16O projectile with 115In target, a well-established activation technique has been employed to measure the excitation functions at low incident energies. The analysis of the present study has been carried out in the framework of the statistical model code pace4. The corrected yields after precursor contribution subtraction for all the measured pxn channels were consistent with the theoretical predictions and attributed to the complete fusion processes. However, a significant enhancement in the measured excitation functions of α-emitting channels was observed and assigned to the incomplete fusion of the projectile. The estimated incomplete fusion fraction has been used to study the effect of several entrance channel parameters on incomplete fusion reaction dynamics. © 2013 American Physical Society.
