A Study of Reaction Dynamics in the Interaction of 14N+59Co System at 32-56 MeV

Abraham Barena Bekele


The present work was done to investigate the reaction mechanisms involved in the interaction of 14N projectile with 59Co target at beam energies ∼32-56 MeV.  The experimentally measured excitation functions available in the literature [2] were compared and analyzed with the statistical model code PACE4 calculation. For non-α emitting channels populated via complete fusion reaction, the measured excitation functions, after correcting them for possible contributions coming from higher charge isobaric precursor decays, were in general found to be in good agreement with theoretical predictions. However, for α-emitting channels, the experimentally measured excitation functions had more production cross-sections than what PACE4 predicted. The observed enhancement in the present case may be attributable to process of incomplete fusion from break-up of 14N projectile. It may be pointed out that incomplete fusion reaction increases with increase in projectile energy. The observation of high incomplete fusion reaction is attributable to the prompt breakup of 14N projectile into α-cluster.
