Proton Triton Interaction

Abstract

A phase shift analysis of the Los Alamos data on $p\ensuremath{-}\mathrm{T}$ scattering for incident protons of 0.708 to 2.548 Mev is carried out using singlet and triplet $s$ and $p$ phase shifts. The large $p$ wave phase shifts obtained are shown to be consistent with the suggested $^{1}P$ resonant level of the $\ensuremath{\alpha}$-particle. The effect of absorption associated with the $\mathrm{T}(p,n){\mathrm{He}}^{3}$ reaction is taken into account by means of a schematic resonance model. A satisfactory fit is obtained with attractive singlet and triplet potentials of depths \ensuremath{\sim}46 Mev and \ensuremath{\sim}11 Mev, respectively. The singlet depth is chosen to give the observed bound state of the $\ensuremath{\alpha}$-particle.
