Momentum space Faddeev calculation of 3He binding energy with N-N P and D waves

The homogeneous version of Coulomb modified Faddeev equations was used to determine the binding energy of 3He. In the 1S0 and 3S1-3D1 subsystem states, a separable representation of the Paris potential was taken for the N-N interaction; whereas less sophisticated separable potentials were employed in the P and D partial waves with j≤2. The influence of these latter higher N-N partial waves on the 3He binding energy was calculated for the first time within the nonperturbative Faddeev equation approach. The trinucleon binding energy differences were found to be compatible with Coulomb energies obtained in the framework of perturbation theory with local N-N potentials
