Studies on alpha-induced astrophysical reactions using the low-energy RI beam separator CRIB

Several alpha-induced astrophysical reactions have been studied at CRIB (CNS Radioactive Ion Beam separator), which is a low-energy RI beam separator at Center for Nuclear Study (CNS) of the University of Tokyo. Two major methods to study them are the alpha resonant scattering, and direct measurements of (alpha, p) reactions using an active or inactive helium gas target. Among the recent studies at CRIB, the measurement of Be-7 + alpha resonant scattering is discussed.
