Tensor-polarized-deuteron capture on deuterium and the D state of He4

The tensor analyzing power T20() of the reaction H2(d,)He4 has been measured at six angles at Ed=9.7 MeV. The result is found to be isotropic with a value of T20=-0.220.014. This analyzing power arises from the interference of S=0 and S=2 capture amplitudes. Since the reaction proceeds predominantly via E2 radiation, the S=2 capture strength can be attributed to S=2, L=2 ground-state admixtures. A heuristic model calculation has been used to show that a 4.8% D-state admixture in the two-deuteron wave function describing He4 can account for the observed T20. © 1984 The American Physical Society.
