   Resolved parameters for MLBW formula were given in the energy  
   region from 1.0e-5 eV to 100 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    
   3.1+-0.2 and 1.7+-0.2 barns, respectively/5/.  The scattering  
   radius was assumed to be 4.5 fermi instead of 3.6 fermi in     
   ref./5/.  Calculated 2200 m/sec cross sections and resonance   
   integrals are as follows:
