  We present measurements of differential cross sections and the analyzing
powers A_y, iT11, T20, T21, and T22 at E_c.m.=431.3 keV. In addition, an
excitation function of iT11(theta_c.m.=87.8 degrees) for 431.3 <= E_c.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.
