摘要:The cross section of the nuclear reactions involved in stellar nucleosynthesis are often very diffi- cult to measure directly at stellar energies because of their very low value and/or the radiaoctive nature of the concerned isotopes, often far from the valley of stability. Moreover, this situation can be complicated by the existence of very low energy resonances and/or subthreshold reso- nances. Indirect methods such as transfer reactions and the ANC method offer the possibility to overcome these difficulties. In this context, the transfer reaction method will be presented and then illustrated through the study of two cases, a resonant reaction case, 12C(a,g )16O and a direct (n,g ) capture case, 60Fe(n,g )61Fe
