我们将 70 至 200 MeV 质子实验室能量之间的 p1d 弹性散射的精确分析功率测量与三体 Faddeev 计算进行比较。单独使用 CD-Bonn 核子-核子力会导致对较高能量下的数据进行过度预测，这表明三体 (3 NF) 力可能很重要。 2 p-交换 Tuscon-Melbourne 3 NF 模型经过调整以匹配 Triton 结合能，导致激发函数的形状更好，但效果太大。 @S0556-2813 ~99!51511-2#
We compare precise analyzing power measurements for p1d elastic scattering between 70 and 200 MeV proton laboratory energy with three-body Faddeev calculations. Using the CD-Bonn nucleon-nucleon force alone leads to an overprediction of the data at higher energies, suggesting that three-body (3 NF) forces may be important. The 2 p-exchange Tuscon-Melbourne 3 NF model, adjusted to match the triton binding energy, leads to a better shape for the excitation function but gives too large of an effect. @S0556-2813 ~99!51511-2#
