使用 156 MeV 同步回旋加速器光束同时研究了 $^{2}\mathrm{H}(p,2p)n$ 和 $^{2}\mathrm{H}(p,pn)p$ 反应。输出核子由 NaI 探测器和大型液体闪烁计数器同时检测到，提供能量飞行时间双参数光谱，其中三重微分截面 $\frac{{d}^{3}\ensuremath{\sigma}}{d{\ensuremath{\Omega}}_{1}d{\ensuremath{\Omega}}_{2}d{E}_{1}}$ 是推导出来的。对于合适的角度对，实验光谱显示特征准自由散射峰，或 $p\ensuremath{-}p$ 或 $p\ensuremath{-}n$ 最终状态相互作用峰。实验结果与各种理论预测进行比较；即，简单的观察者模型计算、非能量壳计算，包括多重散射级数的一阶和二阶项，有或没有库仑相互作用，以及扩展到阿马多型模型的中间能量。简要讨论了这些理论计算。
The $^{2}\mathrm{H}(p,2p)n$ and $^{2}\mathrm{H}(p,pn)p$ reactions have been investigated simultaneously using the 156 MeV synchrocyclotron beam. Outgoing nucleons were detected in coincidence by a NaI detector and a large liquid scintillation counter providing energy-time-of-flight-biparametric spectra from which the threefold differential cross sections $\frac{{d}^{3}\ensuremath{\sigma}}{d{\ensuremath{\Omega}}_{1}d{\ensuremath{\Omega}}_{2}d{E}_{1}}$ are deduced. For suitable angle pairs, the experimental spectra show either the characteristic quasi-free scattering peak, or the $p\ensuremath{-}p$ or $p\ensuremath{-}n$ final state interaction peaks. The experimental results are compared with various theoretical predictions; i.e., a simple spectator model calculation, off-energy-shell calculations including first and second order terms of a multiple scattering series, with or without the Coulomb interaction, and extension to intermediate energy of a Amado type model. These theoretical calculations are briefly discussed.
