/sup 4/He(d pol,d)/sup 4/He scattering from 12 to 17 MeV. [Differential cross sections and vector and tensor analyzing powers, phase-shift analysis

Abstract

Differential cross sections and vector and tensor analyzing powers were measured for vector d + /sup 4/He elastic scattering at deuteron lab energies of 12, 14, 15, and 17 MeV. The data were tabulated and compared with predictions from a recent phase-shift analysis, which did not include the present results in the fitting procedure. Significant discrepancies between the predictions and measurements occur, principally for the tensor analyzing powers at backward angles. It is concluded that the present data should be incorporated into the phase-shift analysis to obtain a more realistic solution. 3 figures, 5 tables.
