Reaction Constants forT3(p,n)He3

Abstract

Measurements of the differential and total cross sections for ${\mathrm{T}}^3\mathrm{}(p,n)\mathrm{}{\mathrm{He}}^3$ between the reaction threshold at 1.019 Mev and 2.49 Mev are reported. At the higher energies the neutron emission in the center-of-mass system is highly asymmetric and the energy dependence of the coefficients of a cosine expansion fit to the angular distribution is determined. Evidences for resonance effects are observed at the highest proton energies used, indicating an excited state in the continuum of the intermediate ${\mathrm{He}}^4$ nucleus. The use of the reaction as a neutron source is discussed.
