// Thermal Neutron Scattering
// Koi, Tatsumi (SCCS/SLAC)
//
// Class Description
// Cross Sections 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.
// Class Description - End

// 15-Nov-06 First implementation is done by T. Koi (SLAC/SCCS)
// 070625 create clearCurrentXSData to fix memory leaking by T. Koi
// 080417 Add IsZAApplicable method (return false) by T. Koi
