/ Abstract
Abstract 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 ≈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.
