共鳴領域における核反応断面積・共分散評価手法の進展に関して発表する。$$gamma$$線チャンネルの導入や荷電粒子弾性散乱に対するR行列計算コードの拡張について述べると共に、理論的拘束条件を効果的に用いた共鳴解析手法を示す。また、$$^8$$Beや$$^{17}$$O複合核システムに対する計算コード・解析手法の適用例を示し、さらに中重核に対する今後の展望を述べる。

We present recent progress of nuclear data evaluation method in the resolved resonance range. Our multi-channel R-matrix code now includes photon-channel and computational capability of charged-particle elastic scattering. We also present the physical constraint from the theory in the analysis of experimental data. Example analysis results are shown for $$^8$$Be and $$^{17}$$O compound system. Finally, perspectives are discussed toward the advancement of nuclear data in the resonance region including those for medium-heavy nuclei.
