Proton-deuteron elastic scattering at low energies

We present measurements of differential cross sections and the analyzing powers A{sub y}, iT{sub 11}, T{sub 20}, T{sub 21}, and T{sub 22} at E{sub c.m.}=431.3keV. In addition, an excitation function of iT{sub 11}({theta}{sub c.m.}=87.8{sup o}) for 431.3{<=}E{sub c.m.}{<=}2000keV 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 A{sub y} and iT{sub 11} data are found to be underpredicted by the calculations.
