Question why photoneutron not producing  

Forum: Hadronic Processes
Date: 13 Aug, 2015
From: Amjid Mahmood <Amjid Mahmood>

in my project e- hit target produces gamma these gamma hit secondary targets produces photoneutrons as i don't know how to change physics list so no photo-nuclear reaction is taking place and i am not getting photoneutrons actually i am working on photoneutron producing in medical linac head geometry in head geometry our primary target is tungsten e- hit this tungsten produces gamma these gamma hit head geometry materials( made of tungsten, lead etc ) they encounter photonuclear reaction and produces photoneutron but as i am unable to change physics list so no photonuclear reaction is taking place and i am not getting any photoneutrons.i am sending you my physics list file and main.cc file tell me where to made changes as i didn't make any changes to physicslist.cc file but i made changes to main.cc file i am attaching physicslist.cc origional main.cc and changed main.cc file please tell me where i am making error and how to correct it
