How to use my owner neutron cross section to simulate?

I want to simulate neutron pass through mono crystal bismuth, can I use G4 to simulate this case using my owner cross section?


it is possible to use custom cross sections for Geant4 hadronic model. There are two possibilities:

  1. substitute Geant4 data files by your data files which should have the same format
  2. Customise hadron inelastic and/or hadron elastic physics constructors
