| Outline of Final Research Achievements |
Nuclear reactions in stars are known to play an important role in the nuclear synthesis of elements in our universe. However, the experimental determination of the reaction rates is difficult as the rates are extremely small. Therefore, a systematic evaluation of reaction rates must rely on theoretical calculations. In this study, we described the nuclear structure starting from the fundamental interactions with various approaches. The validity of our approach is confirmed by comparing them with experimental data. We predicted various phenomena for unknown nuclear systems in vacuum as well as in various star environments, where laboratory experiments are difficult. The methods established in this study are practical and directly applicable to astrophysical reactions. Further extension is highly expected.
