Cross section calculations of nuclear reactions in astrophysics

Big Bang is a cosmological model in which the universe is expanding around for 14 billion years. This model predicts that the light nuclei are created in early universe by Big Bang nucleosynthesis. This model also accept that the heavier elements are produced by stellar nucleosynthesis, explosive nucleosynthesis. In this work, transfer reactions which are very important in nuclear astrophysics are analysized by DWBA models. The cross sections of the transfer reactions of nuclei produced in stars and a nova explosions were determined for different potential values. It is observed that the cross sections have significantly changed by depending on potential values. The results of calculations are compatible with experimental data. Key Words: Big Bang, DWBA, Cross Section.
