Thank you very much for the response. Currently I am using the following physics lists:
- G4EmStandardPhysics; - G4EmExtraPhysics with GammaNuclear and MuonNuclear "on"; - QGSP_BERT_HP for hadron; - G4DecayPhysics; - G4RadioactiveDecayPhysics.
But all generated muons are 0eV (at rest when pion is 0eV). Checked several times but still did not sure what was the problem. I just used the ConstructParticle() and ConstructProcess() of above physics lists. Any hint?
Thanks a lot.
