Hello! I’m still new to geant4. I want to get the decay of Co-60 and Cs-137, but unfortunately, I can please help me get the correct histograms. I am uploading all my files here

, can you please help me fix this problem.
I will be grateful for any help, thank you!


Thank you for following the Tips for posting in Geant4 forum.

I tried to run your code but it seems there are few things broken. You may want to take as starting point the rdecay01 example instead.


Thank you very much for the reply. it really works. Can you please tell me, I would like to get the full spectrum of Co60 decay, not individually the loss of particle energy, but I want to combine everything. How can I do this?
