// GEANT4 physics class: G4GammaNuclearReaction - header file for CHIPS
// Created: J.P. Wellisch, following M.Kossov's algorithm. 2000/08/18 
// The last update: J.P. Wellisch, Thu Jun  6 2002.
// 01.09.2008 V.Ivanchenko move inline to source and define interaction name
// 17.02.2009 M.Kossov, now it is recommended to use the G4QCollision process
