Spectra of α particles were measured for ^12,13C + ⁹³Nb 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 α production. The α spectra were analyzed in detail to determine the effect of 1n transfer on an α-production cross section in particular. After accounting for contributions from direct breakup and Be transfer, there is a clear signature of the α particles produced through the break-up process following neutron transfer in the case of a ¹³C induced reaction. This is an interesting result being reported for the strongly bound projectile.
