Spin-orbit effects in optical model analyses of 3He elastic scattering on oxygen isotopes'

Angular distributions of elastically scattered 3He on 16,17,18O at 14 MeV were measured. Optical model analysis of the data has been performed. In the case 16O case, a spin–orbit term is needed to provide better fits of the data at backward angles and this term allows a satisfactory calculation of the 16O(3He, α)15O reaction.
