| Research Abstract |
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.
