The 116Sn(d,p)117Sn l=0 reaction mechanism at intermediate energies

We report measurements of the cross section, proton polarization, and deuteron vector (Ay) and tensor (Ayy) analyzing powers for the 116Sn(d,p)117Sn reaction to the 1+/2 ground state of 117Sn at Ed=79.0 MeV. The polarization was observed as the analyzing power in the time-reversed 117Sn(p,d)116Sn reaction. Adiabatic model calculations of the deuteron elastic channel reveal significant 3D-wave breakup contributions to the elastic cross section. Satisfactory agreement with the transfer reaction data is nevertheless obtained using adiabatic calculations which include only 3S-wave breakup and the bound deuteron D-state. The influence of the deuteron spin-orbit distortions on the polarization and vector analyzing power is reduced through a combination of the effects of angular momentum mismatch and deuteron channel absorption.
