摘要：

In order to improve the description of the N-d vector analyzing powers A(y) and iT(11) (the so-called A, puzzle) a spin-orbit three-body force has been introduced. The L.S term in the NN potential has been modified including a two-parameter three-body function depending on the hyperradius rho. The modification has been performed in channels where the pair of nucleons (i,j) are coupled to spin S-ij = 1 and isospin T-ij = 1. Calculations have been done in the energy region from E-lab = 648 keV up to E-lab= 10 MeV. A noticeable improvement in the description of the polarization observables has been obtained.
