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 ${C}_{y,y}$. 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 ${E}_{\mathrm{d}}=10 \mathrm{and} 20$ MeV reported here show sizeable off-shell effects, which can be related to the different potential behavior in the inner region $r\ensuremath{\lesssim}1.2$ fm.NUCLEAR REACTIONS Off-shell effects in elastic N-d scattering; separable approximation of the Paris potential used together with on-shell equivalent transformations.
