Abstract
Coupled-channel calculations are performed for the () and () reactions between 7 and 60 MeV to study the effect of inelastic couplings in transfer reactions. The effect of treating transfer beyond Born approximation is also addressed. The coupling to the state is found to change the peak cross section by up to 15%. Effects beyond Born approximation lead to a significant renormalization of the cross sections, between 5% and 10% for deuteron energies above 10 MeV and larger than 10% for lower energies. We also performed calculations including the remnant term in the transfer operator, which has a small impact on the ()(g.s.) and ()(g.s.) reactions (where g.s. indicates ground state). Above 30-MeV deuteron energy, the effect of the remnant term is larger than 10% for the ()(, 3.09 MeV) reaction and is found to increase with decreasing neutron separation energy for the 3.09-MeV state of . This is of importance for transfer reactions with weakly bound nuclei.
