Abstract

Angular distributions of cross section were measured for the H2(p, γ)He3 reaction at Ex=9.83, 10.83, 12.78, 15.47, and 16.12 MeV and of analyzing power at Ex=10.83 and 16.12 MeV. The data were fitted by expansions of Legendre and, where appropriate, associated Legendre polynomials. The coefficients of those fits are reported. The data at Ex=10.83 and 16.12 MeV were also analyzed under simplifying assumptions to extract the s=12(E1), s=12(E2), and s=32(E1) transition matrix elements, where s represents the incident channel spin. The results indicate that the data are consistent with a 2(3)% E2 and a 3(5)% s=32(E1) admixture at Ex=10.83(16.12) MeV. These results are discussed in light of other recent experiments and calculations.
