Spectra of $\alpha$ particles were measured for ${}^{12,13}\mathrm{C} + {}^{93}\mathrm{Nb}$ systems at several angles for a bombarding energy of 65 MeV to investigate various reaction mechanisms like direct break up and cluster transfer responsible for $\alpha$ production. The $\alpha$ spectra were analyzed in detail to determine the effect of $1n$ transfer on an $\alpha$-production cross section in particular. After accounting for contributions from direct breakup and Be transfer, there is a clear signature of the $\alpha$ particles produced through the break-up process following neutron transfer in the case of a ${}^{13}\mathrm{C}$ induced reaction. This is an interesting result being reported for the strongly bound projectile.
