The problem I am seeing seems to have nothing to do with cascades, etc. The single elastic hadronic scattering (included via G4HadronElasticPhysicsHP) gives the attached distribution:
which is very surprising, since, I thought, GEANT now uses ENDF, the distribution from which is the following:
Both distributions are for neutron energy of 2.94MeV.
Before I submit a bug report, I would like to check everything, hence my first question:
1) How do I look at the angular differential cross-section directly, so I that can make a plot vs polar angle for this energy?
To remedy this situation, I can use an ENDF cross-section directly, hence my second question 2) How do I tell GEANT to use my cross-sections?
An answer to either question will be appreciated.
