被引用回数：1 パーセンタイル：12.27(Nuclear Science & Technology)The neutron transmission ratio and capture yield for Ta were measured in J-PARC MLF ANNRI to improve the accuracy of resonance parameters. The total cross section was determined from the transmission ratio in the energy range from 0.2 to 150 eV. The capture cross section was obtained from the capture yield using the pulse height weighting technique (PHWT) in the energy range from thermal to 150 eV. The obtained transmission ratio and capture cross-section were fitted by the resonance analysis code, REFIT, and the resonance parameters were determined below 150 eV. It was also discussed the correlations caused by fitting based on statistical uncertainty and correlations for systematic uncertainty based on sample thickness in the transmission measurements.

原子炉構造材に含まれIAEAのクリアランスの対象となっているTaの中性子断面積および共鳴パラメータの高精度化を目指し、J-PARC・MLF・ANNRIにて中性子捕獲断面積と全断面積を測定した。得られた断面積の結果を共鳴解析コードREFITにより解析し、共鳴パラメータを導出した。
