Abstract One of the standout techniques that is stack foil activation technique has been used to calculate excitation functions of evaporation residues formed in the reaction of 14N projectile with 148Nd target at beam energy ≈ 4 − 7 MeV/nucleon in this research. The analysis of presently calculated cross sections with standard theoretical tool PACE4 shows the population of xn/pxn channels through complete fusion only, while the α-emitting channels were found to populate through incomplete fusion as well as complete fusion. These results suggest the breakup of 14N as α + 10B results in incomplete fusion. A connection tied to the collective impact of total asymmetry and total deformation was examined including the asymmetry and deformation effects of both the projectile and the target. Two separate standard reduction methods have been used to reduce the cross-sections of complete fusion and total fusion for present system 14N + 148Nd and earlier measured system 16O + 148Nd, which reveals that 16O induced reactions have more incomplete fusion probability than that of 14N. A suppression in complete fusion functions has been noted for systems 14N + 148Nd and 16O + 148Nd when compared to universal fusion function. It can be inferred from the varying values of suppression factors of 14N and 16O that the possibility of α-breakup differs for 14N and 16O. Moreover, the total fusion functions for 14N + 148Nd and 16O + 148Nd show strong alignment with the universal fusion function.
