Abstract
A phase-shift analysis based on the scattering and polarization data for the reaction He3(p, p)He3 has been made for proton energies between 1.0 and 11.5 MeV. The singlet and triplet S-wave phase shifts are found to be negative and approximately equal; they are in good agreement with the resonating-group calculations of Bransden and Robertson. The P-wave phase shifts are positive and increase with energy; a single-level parametrization of these phase shifts indicates the possible presence of triplet states with Jπ=2-, 1-, 0- at center-of-mass energies 4.74, 6.15, and 7.94 MeV above the p + He3 threshold. All three levels have reduced widths that are comparable with the Wigner limit. The presence of a broad singlet 1- level at 9.8 MeV is indicated with somewhat less confidence.
