MF= 1 General information MT=451 Descriptive data and directory MF= 2 Resonance parameters MT=151 Resolved and unresolved resonance parameters No resolved resonance is given. Unresolved resonance region: 300 eV - 100 keV The parameters were obtained by fitting to the total and caputure cross sections calculated from CCONE /1/. The unresolved parameters should be used only for self-shielding calculation.
