       The resolved resonance parameters were revised.  The upper 
       limit of the resolved resonance region was changed to      
       241.1 keV from 180 keV.  As a result, the total, elastic   
       scattering and capture cross sections were revised between 
       180 and 241.1 keV.

   Resolved parameters for mlbw formula were given in the energy  
   region from 1.0e-5 eV to 180 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    
   0.7+-0.3 and 2.2+-0.3 barns, respectively/5/.  The scattering  
   radius was assumed to be 4.5 fermi instead of 4.0 fermi in     
   ref./5/.
