// P. Arce, June-2014 Conversion neutron_hp to particle_hp
//
// June-2019 - E. Mendoza - re-build "two_body_reaction", to be used by
//  incident charged particles (now isotropic emission in the CMS). 
//  Also restrict nresp use below 20 MeV (for future developments). 
//  Add photon emission when no data available.
