摘要:

我们报告的第一次详细研究的机制参与敲除反应,通过一个质子敲除反应中的残留物和快质子的重合测量,使用S800摄谱仪结合HiRA检测器阵列在NSCL。给出了反应$^9$ Be($^9$ C,$^8$ B+X)Y和反应$^9$ Be($^8$ B,$^7$ Be+X)Y的结果。它们与理论预测的衍射和剥离反应机制,计算在程函模型。数据显示了两种反应机制之间的明显区别,并且所观察到的相应比例通过反应理论很好地再现。该协议支持敲除反应分析的结果及其在稀有同位素光谱学中的应用。

英文摘要:

We report on the first detailed study of the mechanisms involved in knockout reactions, via a coincidence measurement of the residue and fast proton in one-proton knockout reactions, using the S800 spectrograph in combination with the HiRA detector array at the NSCL. Results on the reactions $^9$Be($^9$C,$^8$B+X)Y and $^9$Be($^8$B,$^7$Be+X)Y are presented. They are compared with theoretical predictions for both the diffraction and stripping reaction mechanisms, as calculated in the eikonal model. The data shows a clear distinction between the two reaction mechanisms, and the observed respective proportions are very well reproduced by the reaction theory. This agreement supports the results of knockout reaction analyses and their applications to the spectroscopy of rare isotopes.
