Effects of the He3 D state in the reaction H2(p,γ)He3
Angular distributions of the reaction H2(p,γ)He3 have been measured for Ep from 6.5 to 16 MeV. A comparison of the extracted a2 coefficients with an effective two-body direct calculation indicates a sensitivity to the inclusion of D-state components in the He3 wave function. These calculations use He3 bound-state wave functions generated from Faddeev-type equations. The theoretical three-body He3 ground-state wave functions having D-state probabilities of 5%-9% (D2=-0.224 to -0.236) are consistent with the present data. © 1983 The American Physical Society.
