       The resolved resonance parameters were revised.  The upper 
       limit of the resolved resonance region was changed to      
       364.28 keV from 300 keV.  As a result, the total, elastic  
       scattering and capture cross sections were revised between 
       300 and 363.28 keV.

    Resolved parameters for MLBW formula were given in the energy 
    region from 1.0e-5 eV to 300 keV.  Parameters were taken from 
    ref./5/, for positive resonances.  Parameters for negative    
    resonance were obtained so that the reproduced cross sections 
    for both scattering and capture gave the 2200 m/s values of   
    2.78+-0.24 and 0.59+-0.18 barn, respectively/5/.  The scatter-
    ing radius was assumed to be 4.5 fermi instead of 3.5 fermi in
    ref./5/.
