Study of D+3He and T+3He Reactions by Using Double Folding Potential at Astrophysical Relevant Energies

Aims: The microscopic double folding potential is more superior over the conventional square-well potential as it more realistic to represents the nuclear interactions and the introduction of an imaginary potential provides an effective and compact way to model absorption in nuclear well. Study Design: The computations of nucleus-nucleus potential are implemented in the framework of double folding model function with DDM3Y-Reid and DDM3Y-Paris effective N-N interaction. Among different kind of the effective interaction, the so-called DDM3Y interaction was used in the double folding potential calculations. Methodology: At astrophysical energy regime, the study of the nuclear fusion cross-sections is formidable on account of the massive vastness of the Coulomb barrier, yield in a minute worth of the fusion cross-section. All achievement in the results on S-function towards light particles can gives a clear insights about Big Bang nucleosynthesis. Presently, we have theoretically examined the E dependence of S-function and nuclear fusion σ(E) for fusion reaction of light nuclei for 3He(D,P)4He and 3He(T,N+P)4He nuclear system using complex potential with Coulomb repulsive potential. Results: The calculation of the cross section and S-function cooked in the foundation of the SRTM potential function approach. Conclusion: Theoretical computed results matched with the experimental results.
