Hello Michel,

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
