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

摘要

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 α resonant scattering, and direct measurements of (α, p) reactions using an active or inactive helium gas target. Among the recent studies at CRIB, the measurement of 7~Be+α resonant scattering is discussed.
