Using G4RadioactiveDecayPhysics in the PhysicsList, we tried to launch some isotopes and study their decays. In case we try any isotope with Z>94 (i.e, above Pu) the code gives us a "G4Exception" message issued by G4ParticleGun::SetParticleDefinition() since null pointer was given. No problem with any other isotope we have tried (as Rn220, Th232, Co60 ..), it works fair. We have checked the data base we are using: RadioactiveDecay4.2 and those isotopes are included.
Hi, Thank you for problem report. I checked with examples/extended/hadronic/Hadr06 (which uses G4RadioactiveDecayPhysics), but I can not reproduce the problem. Cm242 is created successfully with commands below and decays into Pu238 + alpha. (see below) Could you explain the detail of your application and environment? Thanks and Cheers, ---- commands --------------- /run/initialize /gun/particle ion /gun/ion 96 242 4 /tracking/verbose 1 /run/beamOn 1 -------------------- ********************************************************************************************************* * G4Track Information: Particle = Cm242, Track ID = 1, Parent ID = 0 ********************************************************************************************************* Step# X Y Z KineE dEStep StepLeng TrakLeng Volume Process 0 0 fm 0 fm 0 fm 14 MeV 0 meV 0 fm 0 fm Water_ts initStep 1 -3.57 um -2.18 um -3.99 um 0 meV 14 MeV 5.78 um 5.78 um Water_ts ionIoni 2 -3.57 um -2.18 um -3.99 um 0 meV 0 meV 0 fm 5.78 um Water_ts RadioactiveDecay
Thans, it was just our problem. We had put a limit in Z. Sorry for the inconveniences
