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