[3I07] Improving Accuracy of Fission Product Yields by Physics-Informed Bayesian Neural Network

*JINGDE CHEN1, yuta mukobara1, chikako isizuka1, satoshi chiba1, tatsuya katabuchi1 (1. Tokyo Institute of Technology)

Keywords:Fission Product Yields, Physics-Informed Bayesian Neural Network, Shell Effect, Odd-Even Effect

ベイジアンニューラルネットワークモデルに殻効果と奇偶効果を導入し、JENDL-5にある232Th, 233, 235, 238Uと239, 241Puの核分裂収率を高精度に再現し、入射エネルギーが1MeVから5MeVまでの核分裂収率を予測し、各実験上のデータを比較し、その予言性能を検証する。
