Nuclear Astrophysics and Structure Studies Using Low‐energy RI Beams at CRIB

CRIB (CNS Radioactive Ion Beam separator) is a low‐energy RI beam separator at the Center for Nuclear Study (CNS) of the University of Tokyo. Using the RI beams at CRIB, Many measurements on proton and alpha resonance scatterings, (α,p) reactions, and others were peformed in recent years, mainly for studying astrophysical reactions and exotic nuclear structure. Among them, the results on the $7Be+p$ and $7Li+α$ resonance scatterings are presented.
