// Author: 2002 J.P. Wellisch
//
// Modified:
// 15.12.2005 G.Folger: migration to non static particles
// 08.06.2006 V.Ivanchenko: remove stopping
// 20.06.2006 G.Folger: Bertini applies to Kaons, i.e. use SetMinEnergy
//            instead of SetMinPionEnergy
// 25.04.2007 G.Folger: Add code for quasielastic
// 31.10.2012 A.Ribon: Use G4MiscBuilder
// 19.03.2013 A.Ribon: Replace LEP with FTFP
// 12.10.2023 V.Ivanchenko added usage of alternative neutron
//            HP model and cross section
