在 KVI Groningen 测量了 130 MeV 偏振氘核束能量下 H-1((d) 右箭头 pp)n 分解反应的分析能力。实验装置覆盖了相空间的很大一部分。获得的选定运动配置的张量分析能力 T-22 与基于各种方法的理论预测进行了比较：使用具有和不具有三核子力 (3NF) 模型的实际核子-核子势的严格 Faddeev 计算、手征微扰理论的预测以及具有显式 Delta 自由度的耦合通道计算。在所提出的配置中，所有预测的结果彼此非常接近，并且不存在显着的 3NF 影响。并非所有数据都能通过理论计算令人满意地再现。
A measurement of the analyzing powers for the H-1((d) over right arrow pp)n breakup reaction at 130 MeV polarized deuteron beam energy was carried out at KVI Groningen. The experimental setup covered a large fraction of the phase space. Obtained tensor analyzing powers T-22 for selected kinematical configurations have been compared to theoretical predictions based on various approaches: the rigorous Faddeev calculations using the realistic nucleon-nucleon potentials with and without three nucleon force (3NF) models, predictions of the chiral perturbation theory, and coupled channel calculations with the explicit Delta degrees of freedom. In the presented configurations the results of all predictions are very close to one another and there are no significant 3NF influences. Not all of the data can be satisfactory reproduced by the theoretical calculations.
