first oft all thank you very much for the fast reply.
So I ran rdecay01 with your macro and it also works for me. I can change the simulated lifetime by changing the lifetime in the "G4ENSDFSTATE2.1"-data.
I will now accurately compare this example with my own simulation to find the reason why my simulation does not work correctly.
So far I can only say that SetThresholdOfHalLife(0.1*ps) should not be the problem because I already set this to a negative value which worked fine in Geant4.10.1.
But I will double check everything now and response later again.
Thanks Michael Mathy
