Measurement of T20 in π+d elastic scattering

Measurements of the tensor polarization T20 in π+d elastic scattering have been performed at θlabd = 15 degrees between Tpi = 116 and 145 MeV. Angular distributions at 133 and 140 MeV were also determined. These results resolve the discrepancy that is 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. 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. It is concluded that the SIN values arose due to insufficient information for a complete analysis. (Author) (37 refs., 2 tabs., 17 figs.)
