测量了250和294 MeV/核子的氘-质子弹性散射的一套完整的高精度分析本领。这些数据和以前存在的数据集的截面在类似的能量进行比较的结果，三核子Faddeev计算的基础上，现代核子核子（）势单独或结合两个模型的三核子力：图森墨尔本99和厄巴纳九。在c.m.发现了纯理论和数据之间的巨大差异，这是目前的三核子力所不能解决的。所有氘核分析能力和横截面的后向角。由于只有很小的相对论效应被发现的氘核分析功率和截面，包括短程分量的三核子力可能需要得到一个更好的描述的数据。
A complete high-precision set of deuteron analyzing powers for elastic deuteron-proton () scattering at 250 and 294 MeV/nucleon has been measured. These data and previously existing data sets for the cross section at similar energies are compared to the results of three-nucleon Faddeev calculations based on modern nucleon-nucleon () potentials alone or combined with two models of three-nucleon forces: the Tucson-Melbourne 99 and Urbana IX. Large discrepancies between puretheory and data, which are not resolved by the current three-nucleon forces, were found at c.m. backward anglesfor all the deuteron analyzing powers and the cross section. Because only small relativistic effects were found for the deuteron analyzing powers and the cross section, the inclusion of short-range components of the three-nucleon force is probably required to get a better description of the data.
