Abstract

Experimental studies on astrophysical reactions involving radioactive isotopes (RI) often accompany technical challenges. Studies on such nuclear reactions have been conducted at the low-energy RI beam separator CRIB, operated by Center for Nuclear Study, the University of Tokyo. We discuss two cases of astrophysical reaction studies at CRIB; one is for the ⁷Be+n reactions which may affect the primordial ⁷Li abundance in the Big-Bang nucleosynthesis, and the other is for the ²²Mg(α, p) reaction relevantin X-raybursts.
