0029 // Class Description:
0030 //
0031 // Cross Sections for a high precision (based on evaluated data
0032 // libraries) description of themal neutron scattering below 4 eV;
0033 // Based on Thermal neutron scattering files
0034 // from the evaluated nuclear data files ENDF/B-VI, Release2
0035 // To be used in your physics list in case you need this physics.
0036 // In this case you want to register an object of this class with
0037 // the corresponding process.
