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 {sup 8}Li and {sup 8}B, 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 {sup 16}O(p,gamma){sup 17}F{sub gs}(5/2{sup +}) and {sup 16}O(p,gamma){sup 17}F{sub ex}(1/2{sup +}) capture reactions. We also computed the nucleosynthesis cross sections for the {sup 7}Li(n,gamma){sup 8}Li{sub gs}, {sup 8}Li(n,gamma){sup 9}Li{sub gs} and {sup 8}B(p,gamma){sup 9}C{sub gs} capture reactions.
