Abstract
Measurements of the (d→,γHe cross section σ(θ), the vector analyzing power (θ), and the tensor analyzing power (θ) have been obtained at (lab)=14.7 and 1.2 MeV and (lab)≤0.8 MeV; the spherical tensor analyzing power (θ) was also measured at (lab)=14.7 MeV. (130°) and (130°) were measured at eight bombarding energies between (lab)=0.8 and 14.7 MeV and (130°) at ten energies between (lab)=5.4 and 14.7 MeV. A transition-matrix element analysis is performed by fitting to the available angular distribution data at (lab)≤0.8 MeV and at (lab)=1.2 and 14.7 MeV. The data are compared to the results of a multichannel resonating group model (MCRGM) calculation. The MCRGM model includes the tensor force in calculating both the continuum and bound states and provides a fairly good description of the data, especially above =5 MeV. This calculation predicts a D-state probability in arising from the relative motion between the two deuterons of =2.2%.
