| Outline of Final Research Achievements |
Main subject of this study is analysis of the astrophysical S-factor of the Big Bang nucleosynthesis using the ab-initio nuclear reaction theory. The large-scale numerical computation using the super computer was carried out to analyze nuclear reaction rate needed in the big bang theory and the 4He nucleosynthesis in the star. Particularly, d(d,γ)4He, t d(d,n)3He and d(d,p)t reaction was studied in detail. The new technique is proposed and showed the usefulness on one of methodology, in which correlated Gaussian basis is combined with the triple global vector.
