Light radioactive nuclei play an important role in many astrophysical environments. Due to very low cross sections of some neutron and proton capture reactions by these radioactive nuclei at energies of astrophysical interest, direct laboratory measurements are very difficult. For radioactive nuclei such as 8Li and 8B, the direct measurement of neutron capture reactions is impossible. Indirect methods have been applied to overcome these difficulties. In this work we will report on the results and discussion of phenomenological potential models used to determine some proton and neutron capture reactions. As a test we show the results for the 16O(p,γ)17Fgs(5/2+) and 16O(p,γ)17Fex(1/2+) capture reactions. We also computed the nucleosynthesis cross sections for the 7Li(n,γ)8Ligs, 8Li(n,γ)9Ligs and 8B(p,γ)9Cgs capture reactions.
