我们报告的第一个详细的研究的相对重要性的剥离和衍射机制参与核子敲除反应，通过使用一个质子敲除反应后的残留物和快质子的符合测量。测量使用S800摄谱仪与NSCL的HiRA探测器阵列相结合。给出了反应9Be（9C，8B+X）Y和9Be（8B，7Be+X）Y的结果，并与用程函模型计算的两种反应机理的理论预测进行了比较.数据显示出剥离和衍射机制之间的明显区别，并且通过反应理论很好地再现了测量的相对比例。该协议增加了对敲除反应分析结果及其在稀有同位素光谱学中的应用的支持。
We report the first detailed study of the relative importance of the stripping and diffraction mechanisms involved in nucleon knockout reactions, by the use of a coincidence measurement of the residue and fast proton following one-proton knockout reactions. The measurements used the S800 spectrograph in combination with the HiRA detector array at the NSCL. Results for the reactions 9Be(9C,8B+X)Y and 9Be(8B,7Be+X)Y are presented and compared with theoretical predictions for the two reaction mechanisms calculated using the eikonal model. The data show a clear distinction between the stripping and diffraction mechanisms and the measured relative proportions are very well reproduced by the reaction theory. This agreement adds support to the results of knockout reaction analyses and their applications to the spectroscopy of rare isotopes.
