Hello! I used the G4EmstandardPhysics_option4(1,2 3) physics list to simulate the interaction between alpha particle and plastic, and I want to know the energy distribution of the secondary electron. But I cannot find any electron, when I use step-GetTrack()->GetParticleDefinition()->GetParticleName() == “e-” code to find them.

Is the secondary electron was ignored in the G4EmstandardPhysics_option4 or there are some other potential errors in my simulation?

Looking forward to your help, and thank you very much!

Thanks for your suggestion!

When I increase the energy of alpha particle, the secondary electrons appear. Now I think the secondary electron was not ignored for the low energy alpha particle in G4EmstandardPhysics_option4(1,2 3) physics list.
