Abstract

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.

Highlights

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
CRIB [1, 2] is a radio-isotope (RI) beam separator operated by Center for Nuclear Study (CNS), the University of Tokyo, installed in the RIBF facility of RIKEN Nishina Center
Most of the RI beams are produced via direct reactions such as (p, n), (d, p) and (3He, n), taking place at an 8-cm-long gas target with a maximum pressure of 760 Torr
