Scientific paper

Since its publication in 1999, the NACRE compilation of thermonuclear reaction rates of astrophysical interest has been widely used in studies of stellar evolution and concomitant nucleosynthesis processes. In consideration of ever-accumulating experimental data, the NACRE update and extension project is under way in the framework of a Konan-ULB convention. The goal is to ``evaluate'' the existing experimental data, and to provide reliable thermonuclear reaction rates at low-energies as astrophysical applications call for. The phenomenological approaches such as the potential model, R-matrix method, and DWBA are adopted in the evaluation. The astrophysical S-factors of the 7Be(p,γ)8B, 20Ne(p,γ)21Na, 3H(d,n)4He, and 3He(d,p)4He reactions are investigated with those three models, for instance. The experimental S-factor data can be reproduced well by our models.
