Experimental evidence for alpha production following neutron transfer in the C-13 + Nb-93 system

Spectra of alpha particles were measured for C-12,C-13 + Nb-93 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 C-13 induced reaction. This is an interesting result being reported for the strongly bound projectile.
