Abstract

Spectra of $\ensuremath{\alpha}$ 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 $\ensuremath{\alpha}$ production. The $\ensuremath{\alpha}$ spectra were analyzed in detail to determine the effect of $1n$ transfer on an $\ensuremath{\alpha}$-production cross section in particular. After accounting for contributions from direct breakup and Be transfer, there is a clear signature of the $\ensuremath{\alpha}$ 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.
