I posted my message because i made simulation with hydrogen and i obtained this result:

and i made an other one with Li6, it gave me this reasonable result:

Who can tell me wich kind of isotopes have been tested? I have tried Au at 4.9 eV because it is an international standard, i thought a simulation like Geant4 should have correct standards. What should I expect for other isotopes? Thank you Enrico Billi
