Abstract：
This paper described the nuclear astrophysical studies using the unstable ion beam facility GIRAFFE in CIAE, by indirect measurements. We measured the angular distributions for some single proton or neutron transfer reactions, such as⁷Be(d,n)⁸B,¹¹C(d,n)¹²N,⁸Li(d,p)⁹Li and¹³N(d,n)¹⁴O in inverse kinematics, and derived the astrophysicalS-factors or reaction rates of⁷Be(p,γ)⁸B,¹¹C(p,γ)¹²N,⁸Li(n,γ)⁹Li,¹³N(p,γ)¹⁴O by asymptotic normalization coefficient, spectroscopic factor, and R-matrix approach at astrophysically relevant energies. Some most recent progress of nuclear astrophyiscal work in CIAE are also summarized.
