Aiming to investigate the incomplete fusion processes at low projectile energies, experiments have been carried out for the 13C + 169Tm system at ≈ 4-7 MeV/A. Excitation functions for several heavy residues likely to be populated via complete and incomplete fusion processes have been measured using heavy recoil residue catcher technique followed by γ- ray spectroscopy. The measured cross-sections for the complete fusion (xn and pxn) channels are compared with the statistical model code PACE4, consistently using the same set of parameters. The complete fusion channels are found to be consistent with the model calculations. However, the cross-sections for all the measured α-emitting channels are found to be significantly enhanced over the calculations. Analysis of data indicate a significant fraction of incomplete fusion even at energies as low as 17% above barrier. The present results are discussed in light of the Morgenstern’s systematics. Incomplete fusion strength function is found to be relatively large for alpha cluster projectile i.e. for 12C as compared to one neutron excess 13C projectile.
