摘要：

A simple formulation of low-energy transfer reactions is developed within the R-matrix method. This parametrization is shown to provide the energy dependence of the S-factor with a good accuracy. We study the He-3(He-3,2p)He-4, H-2(d,p)H-3 and Li-6(p,alpha)He-3 reactions as typical examples. From these fits we analyze electron screening effects. Screening potentials are determined with an error analysis based on experimental errors as well as on theoretical uncertainties. (C) 1998 Elsevier Science B.V.
