Deuteron-${}^3\mathrm{H}\mathrm{e}$ scattering using nucleon-${}^3\mathrm{H}\mathrm{e}$ optical potentials fitted to four-body amplitudes

Deuteron-${}^3\mathrm{H}\mathrm{e}$ reactions in the 15 to 40 MeV range are studied using a three-body model where the constructed nonlocal optical potentials rely on rigorous nucleon-${}^3\mathrm{H}\mathrm{e}$ scattering calculations. The differential cross section for the elastic scattering and neutron transfer reaction is predicted quite well up to 90 deg scattering angles. The importance of the Pauli term in complex potentials is demonstrated.
