Low energy incomplete fusion and the role of input angular momenta

Abstract

Aiming to investigate the incomplete fusion processes at low projectile energies, experiments have been carried out for the 14N + 169Tm system at ≈ 4–7 MeV/A. Excitation functions for several residues likely to be populated via complete and incomplete fusion processes have been measured for the first time using heavy recoil residue catcher technique followed by γ-ray spectroscopy. The measured excitation functions are compared with the calculations based on the available statistical model codes. The incomplete fusion strength function is found to increase with the projectile energy. An attempt has been made to compare the present system with an semi-empirical code MARC for incomplete fusion.
