摘要：

We present measurements of the analyzing powers A(y) and iT(11) for proton-deuteron scattering at E-c.m. = 432 keV. Calculations using a realistic nucleon-nucleon potential (Argonne V18) are found to underpredict both analyzing powers by approximate to 40%. The inclusion of the Urbana three-nucleon interaction does not significantly modify the calculated analyzing powers. Due to its short range, it is difficult for this three-nucleon interaction to affect A(y) and iT(11) at this low energy. The origin of the discrepancy remains an open question.
