Proton-3H scattering calculation: Elastic and charge-exchange reactions up to 30 MeV

Proton-H-3 elastic scattering and charge-exchange reaction H-3(p,n)He-3 in the energy regime above the four-nucleon breakup threshold are described in the momentum-space transition operator framework. Fully converged results are obtained by using realistic two-nucleon potentials and a two-proton Coulomb force as dynamic input. Differential cross section, proton analyzing power, outgoing neutron polarization, and proton-to-neutron polarization transfer coefficients are calculated between 6 and 30 MeV proton beam energy. Good agreement with the experimental data is found for the differential cross section both in elastic and charge-exchange reactions; the latter shows a complicated energy and angular dependence. The most sizable discrepancies between predictions and data are found for the proton analyzing power and outgoing neutron polarization in the charge-exchange reaction, while the respective proton-to-neutron polarization transfer coefficients are well described by the calculations.
