Sensitivity of N-d polarization observables on the off-shell behavior of the N-N interaction

We demonstrate the off-shell sensitivity of second-order polarization observables in elastic N-d scattering by means of the spin-correlation parameter Cy,y. For the N-N interaction we start with the Paris potential and then generate on-shell equivalent separable potentials with different off-shell properties. The results for Ed=10 and 20 MeV reported here show sizeable off-shell effects, which can be related to the different potential behavior in the inner region r1.2 fm.NUCLEAR REACTIONS Off-shell effects in elastic N-d scattering; separable approximation of the Paris potential used together with on-shell equivalent transformations.
