We present measurements of differential cross sections and the analyzing powers Ay, iT11, T20, T21, and T22 at Ec.m.=431.3 keV. In addition, an excitation function of iT11 (θc.m.=87.8°) for 431.3<~Ec.m.<~2000 keV is presented. These data are compared to calculations employing realistic nucleon-nucleon interactions, both with and without three-nucleon forces. Excellent agreement with the tensor analyzing powers and cross section is found, while the Ay and iT11 data are found to be underpredicted by the calculations.
