Effects of non-nucleonic degrees of freedom in the {ital D}({ital p{searrow}{bold ,}}{bold {gamma}}){sup {bold 3}}{ital H}{ital e} and {ital p}({ital d{searrow}{bold ,{gamma}}}{bold )}{sup {bold 3}}{ital H}{ital e} reactions

Measurements of the D({ital p}{searrow},{gamma}){sup 3}He and {ital p}({ital d}{searrow},{gamma}){sup 3}He reactions below {ital E}{sub {ital p},{ital d}}=80 keV are compared to the results of calculations based on correlated hyperspherical harmonic wave functions obtained from realistic interactions with full inclusion of Coulomb distortion in the initial continuum state, and a nuclear current operator with one- and two-body components. Dramatic effects due to the tensor force and the associated two-body (meson-exchange) interaction currents are observed in the vector and, to some extent, tensor analyzing powers for the first time. The extrapolation to zero energy leads to an {ital S}-factor value of {ital S}({ital E}=0)=0.165{plus_minus}0.014 eVb, in reasonable agreement with theory. {copyright} {ital 1996 The American Physical Society.}Measurements of the D(p-->, gamma )3He and p(d-->, gamma )3He reactions below Ep,d = 80 keV are compared to the results of calculations based oncorrelated hyperspherical harmonic wave functions obtained from realistic interactions with full inclusion of Coulomb distortion in the initial continuum state, and anuclear current operator with one- and two-body components.
