Description
Experimental angular distributions for the

Sn elastic and inelastic (projectile and target excitations)
scattering, and for the neutron stripping reaction, have been obtained at

4 MeV). Coupled channel and coupled reaction channel
calculations were performed and both describe satisfactorily the experimental data sets. The

Li inelastic
excitation (using a rotational model), as well as the projectile coupling to the continuum (
α
plus a tritium particle)
play a fundamental role on the proper description of elastic, inelastic, and transfer channels. Couplings to the
one-neutron stripping channel do not significantly affect the theoretical elastic scattering angular distributions.
The spectroscopic amplitudes of the transfer channel were obtained through a shell model calculation. The
theoretical angular distributions for the one-neutron stripping reaction agreed with the experimental data.
