Study of cluster correlation in atomic nuclei using knock-out reaction

我们提出用α敲除反应来研究原子核中的团簇关联。为此，我们研制了一台硅计数器望远镜来探测被击倒的阿尔法粒子，并在Tandem-Van de Graff加速器设施上测试了它的性能。利用这台硅计数器望远镜，我们测量了大阪大学核物理研究中心类似于α敲除反应的α转移反应。我们还测量了400 MeV下^&lt；24&gt；Mg的α非弹性散射。在扭曲波Born近似计算的基础上，我们进行了多极分解分析，发现了几个发展良好的α团簇状态的候选者。

We proposed to study the cluster correlation in the atomic nuclei by means of the alpha knock-out reaction. For this purpose, we developed a Si counter telescope to detect knocked-out alpha particles, and tested its performance at the Tandem-Van de Graff accelerator facility. Using this Si counter telescope, we measured ^<16>O(d,^6Li) reaction which is the alpha transfer reaction analogous to the alpha knock-out reaction at Research Center for Nuclear Physics, Osaka University. We also measured alpha inelastic scattering from ^<24>Mg at 400 MeV. We performed the multipole decomposition analysis on the basis of the distorted-wave Born-approximation calculation, and found several candidates for the well-developed alpha cluster states.
