Abstract: Excitation functions of nine evaporation residues populated through complete and/or incomplete fusion in 14N + 124Sn system in the projectile energy range ≈4−7 MeV/nucleon have been measured. Recoil catcher activation technique using offline γ -ray spectrometry has been employed in these measurements. The evaporation residues produced through xn and pxn channels are found to be well reproduced by the theoretical predictions of PACE-4. In case of evaporation residues produced through α-emitting channels, significant enhancement in the measured excitation functions over their theoretical predictions has been observed. This enhancement indicates that these α-emitting channels are attributed to the incomplete fusion process. The comparison of present study with literature data also shows that the ICF probability depends on various entrance channel parameters. A new combined parameter has been found to explain more precisely the ICF dynamics than other entrance channel parameters.
