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.

我们提出用α敲除反应研究原子核中的团簇关联。为此，我们开发了一个硅计数器望远镜，以检测敲出的α粒子，并测试其性能在串联范德格拉夫加速器设施。使用这种硅计数器望远镜，我们测量了^<16>O（d，^6Li）反应，这是与大坂大学核物理研究中心的α敲除反应类似的α转移反应。我们还测量了400 MeV的α-Mg的非弹性散射<24>。我们进行了多极分解分析的基础上的扭曲波玻恩近似计算，并找到了几个候选人的发达的α集团状态。
