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.13.75. Cs,21.45.+v,24.70.+s,
