Thanks to all of you for the help with the superheavies!
I have learned a lot from the discussion and in the end I followed the advice of Pico (thank you) and changed the nucleusLimits in the Geant source code directly!
I also found another thing in the source code in: source/processes/hadronic/models/de_excitation/photon_evaporation/src/G4DiscreteGammaDeexcitation.cc which returns False if nucleusZ>98. I increased this limit too.
I can now produce a file for a superheavy nucleus and it decays nicely (via alpha -- detected in the Si detectors) into one excited state in the the daughter nucleus. So far so good. But the gamma decay of the daughter does not turn out right. At the moment I leave this one state to decay with either of three gammas and then looking at the transitions coming out. The three gammas are present in my Ge spectrum at the right energies but the relative intensities are wrong. If I modify the intensities the peaks don't react correspondingly. (the three gammas are followed by transitions to all end up in the ground state eventually)
I have a feeling that there's another array or limit of Z or A that is checked somewhere that I have not been able to find which limits my daughter to decay. Does anyone have any clues why it does not work as expected?
I would be grateful for a reply. Thanks, Lise-Lotte
