The parameters for a negative resonance remain unchanged from JENDL-4.0. Unresolved resonance region: 10 keV - 300 keV The parameters were obtained by fitting to the total and caputure cross sections calculated from CCONE /3/. The unresolved parameters should be used only for self-shielding calculation.
