Study of Alpha-Cluster Structure for Astrophysical Reactions

研究的主要背景是(1)放射性核（11C, 18Ne, 30S, 22Mg）上恒星（α,p）反应的研究，(2)MSTPC时间投影主动靶室的研制，(3)44Ti束流的研制。研究了共振α弹性散射以阐明簇在（α,p）反应中的作用。首次证明了α团簇共振在（α,p）反应中的重要作用。首次成功地用RI光束对（α,p）反应进行了广泛的测量。部分工作已总结为博士论文，并准备出版。

The main context of the research is (1) study of stellar (α,p) reactions on radioactive nuclei (11C, 18Ne, 30S, and 22Mg), (2) development of MSTPC time-projection active target chamber, (3) a beam development of 44Ti. Resonant α elastic scattering was also investigated to clarify the role of a cluster in the (α,p) reactions. The important role of α cluster resonances for the (α,p) reactions has been demonstrated for the first time Successful, extensive measurements of the (α,p) reactions with RI beams were made for the first time. Some parts of the work have been summarized for Ph. D. thesis and also being prepared for publications.
