Breakup following neutron transfer for the 7Li + 144Sm system

We have analyzed the backward angle quasi-elastic excitation function and the barrier distribution for the 7Li + 144Sm system by considering not only the direct breakup of the projectile, the inelastic excitations of the target and the?one-neutron transfer channel, but also the sequential breakup of 7Li as a two-step process: the stripping of one neutron followed by the breakup of 6Li. The agreement of the theoretical calculations with the experimental barrier distribution is good, even without any fit procedure. This result confirms some recent experimental evidences showing the importance of this two-step process to 7Li breakup.
