Low energy $n-\nuc{3}{H}$ scattering : a novel testground for nuclear interaction
arXiv:nucl-th/0412089 · doi:10.1103/PhysRevC.71.034004
Abstract
The low energy $n-\nuc{3}{H}$ elastic cross sections near the resonance peak are calculated by solving the 4-nucleon problem with realistic NN interactions. Three different methods -- Alt, Grassberger and Shandas (AGS), 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.
