Abstract
Time delay analysis of neutron-alpha resonant scattering cross sections supports characterization of the lowest 3/2+ level in 5He as fundamentally an n-α resonance on the second Riemann energy sheet of both n-α and deuteron-3H channels, with an associated shadow pole on a different unphysical sheet that, through its associated zero on the physical sheet, contributes to the large 4He(n,d)3H cross section.
