Abstract：
The MeV photon beam will be produced by Shanghai Laser Electron γ Source which is being proposed. Based on it, a series of nuclear astrophysics experiments can be carried on and the reaction rates of these reactions can be determined accurately. In this paper, the reaction rates of the key reaction ¹²C(α,γ)¹⁶O are calculated according to experiments data and theoretical results, and the mean value and statistical error of these calculated rates are evaluated. The new set of parameters of reaction rate formula are obtained though fitting above results. The reaction rate and its error at T₉=0.2 in which ¹²C(α,γ)¹⁶O occurred are extracted, and the screening effects of reaction rate are discussed.
