The tensor analyzing power T20 for d-p elastic scattering at or near θc.m.=180° has been measured at sixteen deuteron beam energies between 0.3 and 2.3 GeV. In marked disagreement with earlier work, large negative values (|T20|>0.6) are found at all energies in this range, with a dip to T20=-1.25 at Td=0.5 GeV. The present results are compared with various model calculations.
