Abstract
It was suggested by Feshbach 1) that the optical model potential might contain a spin-spin term of the form I.σ (where I and σ are respectively the target and projectile spin operators) which would give rise to different scattering for the various possible channel spins. One manifestation of this potential would be a spin dependence of the s-wave neutron strength function So. The effect would be more prominent in high spin nuclei.
