Low-energy incomplete fusion and its sensitivity to projectile structure

To study the heavy-ion-induced reactions, particularly complete and incomplete fusion, the excitation functions for 16O+165Ho interactions at energies ≈73-105 MeV have been measured using a well-established activation technique. The excitation functions have been compared with the predictions of the statistical model code pace4. The comparison advises that the formation of xn and pxn channels is governed only via complete fusion processes. Even after correction for precursor contribution, a significant enhancement in the production of α-emitting channels may be attributed to incomplete fusion contribution. Furthermore, in order to understand incomplete fusion reactions in a more conclusive way, the incomplete fusion fraction has been analyzed with the existing data for 12C and 20Ne beams on the same target (165Ho) where a strong projectile structure effect has been observed, which correlates incomplete fusion reaction dynamics with the α-Q value of the projectile. © 2013 American Physical Society.
