I'm using G4 9.3.
I find very different results when I send high energy neutrons (tens of MeV) in a liquid xenon target by changing only the elastic scattering model for hadrons:
- with G4HadronElastic.
(apart from this change, the Physics list I'm using is the one of the cosmicray_charging example, available up to the 9.2 G4 version)
With the G4LElastic neutron can penetrate much more deeply in the LXe.
In a similar check with a light target (water) I could not see any difference even after a large depth (up to 5m). So the difference seems limited to high A nuclei.
Can anybody explain me the difference between the two models? And, is one of the two clearly preferable against the other one ( ... I mean , is there any validation? )
Thank you, Marco
