Low energy n-3H 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-3H total cross section.
