Hi there, I've encountered a problem with the latest release of the binary cascade model (see below). Verbose output of the simulation is available by email. Best Regards, Iwan I am running geant4.6.2 with gcc 3.2.2 under redhat 9.0 G4BinaryLightIonReaction.cc: Cannot correct 4-momentum of cascade particles In src/G4BinaryLightIonReaction.cc, line 354: ===> G4BinaryCasacde::ApplyCollision() G4HadronicProcess failed in ApplyYourself call for - Particle energy[GeV] = 0.204 - Material = Water - Particle type = He2[0.0] *** G4Exception : 007 issued by : G4HadronicProcess GeneralPostStepDoIt failed. *** Fatal Exception *** core dump *** *** G4Exception: Aborting execution *** Aborted
