Question finding secondary neutrons 

Forum: Particles
Date: 22 Jul, 2009
From: Kent Wong <Kent Wong>

Fermilab is planning on using a 400 MeV proton beam through a 42cm polystyrene block bringing the energy down to 250 MeV. I need to calculate the ratio of the proton fluence to neutron fluence at a planar target and the energy spectrum of the neutrons. I have all my .hh and .cc files required but I don't know the Geant4 Command that will allow me the extract the number of secondary neutrons, even if there are other secondary particles being produced in the polystyrene block.

Does anyone know the command ?

Thank you, Kent
