Hello, The G4LEAlphaInelastic model, which is used in the HIIonLEP class in the hadrontherapy example, should not be applied above 100 MeV. A possiblity to simulate inelastic interactions of alpha particles for energies > 100 MeV is to use the G4LEAlphaInelastic (for energies < 100 MeV) and the G4BinaryLightIonReaction (for higher energies): G4double ionLEPMaxEnergy = 100. * MeV; G4double ionBinaryMinEnergy = 95. * MeV; G4double ionBinaryMaxEnergy = 1. * GeV; G4BinaryLightIonReaction* ionBinaryModel = new G4BinaryLightIonReaction; ionBinaryModel -> SetMinEnergy(ionBinaryMinEnergy); ionBinaryModel -> SetMaxEnergy(ionBinaryMaxEnergy); G4LEAlphaInelastic* alphaLEPModel = new G4LEAlphaInelastic; alphaLEPModel -> SetMaxEnergy(ionLEPMaxEnergy); G4AlphaInelasticProcess* alphaInelasticProcess = new G4AlphaInelasticProcess("inelastic-alpha"); alphaInelasticProcess -> RegisterMe(alphaLEPModel); alphaInelasticProcess -> RegisterMe(ionBinaryModel); particle = G4Alpha::Alpha(); processManager = particle -> GetProcessManager(); processManager -> AddDiscreteProcess(alphaInelasticProcess); The G4BinaryLightIonReaction model can also be applied to other ions like deuterons and tritons.
