Outline of Final Research Achievements

The 130Sn(d,p)131Sn reaction is measured in the inverse kinematics on April 2022 to deduce the 130Sn(n,γ)131Sn reaction rate which is important for a nucleosynthesis network calculation code to make the characteristic peak at the mass number 130 of the rapid neutron capture process(r process) in neutron star merger . The experimental equipment was prepared, and the performance was evaluated by a test experiment. The experiment was performed on 10 days after the study period. Experimental data were taken and the analysis is in progress.

Academic Significance and Societal Importance of the Research Achievements

(d,p)反応は核構造研究に有力な道具であることが知られている。しかし、重い不安定核ビームを用いた逆運動学での測定では十分な励起エネルギー分解能と十分な統計精度を両立させることが難しかった。本研究では、理化学研究所RIビームファクトリーで作られた高輝度の中性子過剰核(130Sn)ビームを使うことで、十分な分解能と統計精度での測定が可能になる。rプロセスの質量数130のピーク周辺のrプロセスの流れについて議論できると期待する。
