Re: Question LElastic vs hElastic (Maria Gatu Johnson)

Hi Maria,

   There have been many changes between Geant4 versions 5 and 9, including improvements in the high precision neutron code.  These may include a decrease
in cross section for given isotopes, but in any case, the later versions of
HP neutron should be considered more correct.
   You will not lose any particles in SteppingAction unless you specifically 
remove particles in that code, which is not a good idea in general.
   hElastic designates the use of a more general elastic scattering code that 
tries to take the best elastic scattering model in each energy range for each particle.  Depending on the physics list used it could be G4UHadronElasticProcess
or G4HadronElasticProcess.  LElastic refers to the older GHEISHA-style elastic
scattering model.

Dennis
