摘要：

R-matrix analyses have been performed for the 7Li(t, n) 9Be and 7Li(3He, p) 9Be reactions, which are thought to be of importance in primordial abundance of 9Be. All available data were compiled and used in the R-matrix analysis. The resonance parameters are compared with previous works. The resulting fit was used to extract an improved determination of the reaction rate for both reactions. The present rates of 7Li(t, n0) 9Be at T = 0.3-3 GK are about 7.5-28.9% lower than the values of Brune et al. and are larger than the rates of Barhoumi et al. by up to 28.1%. Our 7Li(3He, p0) 9Be rates are higher than those of Yan et al. by no more than 29% and differ within 21% from those of Rath et al. over 0.1-3.0 GK.
