Low energy $n-\nuc{3}{H}$ scattering : A novel testground for nuclear interactions

Abstract : The low energy $n-\nuc{3}{H}$ elastic cross sections near the resonance peak are calculated by solving the four-nucleon problem with realistic NN interactions. Three different methods -- Alt, Grassberger and Shandas ; hyperspherical harmonics; and Faddeev-Yakubovsky -- have been used and their respective results are compared. We conclude on a failure of the existing NN forces to reproduce the $n-\nuc{3}{H}$ total cross section.
