In a recent experiment investigating the origin of the \(\alpha \) particle yield in the \(^7\)Li + \(^{144}\) Sm system the measured \(\alpha + d\) coincidences at a bombarding energy of 30 MeV were shown to arise from decay of the 2.186-MeV \(3^+\) resonance of \(^6\)Li. In this work we demonstrate that the laboratory frame \(\alpha \) particle angular distribution extracted from these data can be well described by a standard coupled channels Born approximation calculation and, furthermore, that the mechanism is dominated by direct, one-step single neutron stripping to the \(3^+\) resonance, as shown previously for the \(^7\)Li + \(^{65}\)Cu and \(^{93}\)Nb systems.

在一项最近的实验中,研究了\(^ 7 \) Li + \(^ {144} \)  Sm系统中\(\ alpha \)粒子产量的起源,测得的\(\ alpha + d \)符合在30 MeV的轰击能量被证明是由\(^ 6 \) Li的2.186-MeV \(3 ^ + \)共振的衰减引起的。在这项工作中,我们证明了从这些数据中提取的实验室框架\(\ alpha \)粒子角度分布可以通过标准耦合通道Born近似计算来很好地描述,此外,该机理主要由直接的单步单峰控制中子剥离到\(3 ^ + \)共振,如先前所示\(^ 7 \) Li + \(^ {65} \) Cu和\(^ {93} \) Nb系统。
