Measurement oft20inπ+d elastic scattering

Measurements of the tensor polarization t/sub 20/ in ..pi../sup +/d elastic scattering have been performed at theta/sub d//sup lab/ = 15/sup 0/ between T/sub ..pi../ = 116 and 145 MeV. Angular distributions at 133 and 140 MeV were also determined. These results resolve the discrepancy that has existed between the measurements made by other groups at SIN and at LAMPF, as our values are negative for all energies and angles investigated and consistent with the LAMPF data. Our results are also in good agreement with the corresponding measurements of analyzing powers. Lack of any significant oscillatory nature is in general agreement with theories at these kinematic regions and does not lend support to exotic effects such as dibaryon resonances.
