We have measured the process pd → He³γ in the energy region of Δ(1236) nucleon isobar excitation. At an incident proton energy of 462 MeV, data were assembled for center of mass angles of 45°, 60°, 75°, 90°, 105°, 120°, and 135°. We also measured the energy dependence of the 90° cross-section in the center of mass, for incident proton energies of 377, 462 and 576 MeV. We discuss implications for T-invariance in the electromagnetic interaction by a detailed balance comparison with the inverse reaction. In addition, we present an angular distribution for the process pd → He³π° at an incident proton energy of 462, as well as limited angular distributions at 377 and 576 MeV.
