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 $E_{\mathrm{d}}=10\mathrm{} \mathrm{and} 20$ MeV reported here show sizeable off-shell effects, which can be related to the different potential behavior in the inner region $r\lesssim 1.2$ fm.
