Three-nucleon observables and the low-energy behavior of triplet P-wave nucleon-nucleon interactions

Using nonlocal NN interactions which reproduce the three-nucleon binding energies, this work investigates the dependence of the theoretical p-d and n-d elastic scattering results on the triplet P-wave NN interactions. The low-energy tensor analyzing powers T₂₀ and T₂₁ are found to be also sensitive to the triplet P-wave interactions. A link seems to exists between the N-N and N-d analyzing powers which makes it possible to define sets of low-energy (between 1 and 100 MeV) modified nonlocal triplet P-wave interactions capable of reproducing most of the known experimental N-d elastic scattering data up to 30 MeV. The same results could be achieved with analogously modified local triplet P-wave interactions. Based on these results, a nonlocal interaction is constructed, which reproduces simultaneously the N-N data and most of the known N-d elastic scattering experiments up to 30 MeV.
