// Class Description:
|
|
//
|
|
// Final State Generators 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.
