hello Geant4 users,
I want to ask about the meaning of the following commands:
/process/em/setDirectionalSplitting true
/process/em/setDirectionalSplittingTarget 1000 0 0 mm
/process/em/setDirectionalSplittingRadius 10 cm
/process/em/setSecBiasing eBrem world 100 100 MeV
/process/em/setSecBiasing Rayl world 100 100 MeV
/process/em/setSecBiasing phot world 100 100 MeV
/process/em/setSecBiasing compt world 100 100 MeV
/process/em/setSecBiasing annihil world 100 100 MeV
and the difference between these two commands
/process/em/setSecBiasing eBrem world 100 100 MeV
/process/em/setBiasingFactor eBrem 200 true
best regards.
