Abstract
We present measurements of the analyzing powers A(y) and iT(11) for pr oton-deuteron scattering at E-c.m. = 432 keV. Calculations using a rea listic nucleon-nucleon potential (Argonne V18) are found to underpredi ct both analyzing powers by approximate to 40%. The inclusion of the U rbana three-nucleon interaction does not significantly modify the calc ulated analyzing powers. Due to its short range, it is difficult for t his three-nucleon interaction to affect A(y) and iT(11) at this low en ergy. The origin of the discrepancy remains an open question.
