Tensor and vector analyzing powers for the ²H (d,γ) ⁴He reaction have been obtained as a function of angle at E_d(lab) = 20, 30, and 50 MeV. Differential cross sections were extracted at 30 and 50 MeV. Data for A_yy(θ) and A_y(θ) were obtained at all three energies, while T₂₀(θ) was also measured at E_d(lab) = 50 MeV. A direct capture calculation was performed and compared to the data. This calculation assumes point deuterons and that the reaction proceeds primarily via E2 radiation in this energy region. A value of …
