None Problem with U-233 fission 

Forum: Hadronic Processes
Date: 18 Apr, 2007
From: Bari Osmanov <Bari Osmanov>

 Hello, everyone. I am simulating the fission of U-233 by 
thermal and fast neutrons.
 I was able to get fission fragments through G4ParaFissionModel. However,
when I sum up the mass numbers of fission fragments and fission neutrons,
 I get 239, i.e. it looks like GEANT uses the data for 238U+n fission.
 However, I clearly introduced U-233 target in my detector construction.
 Anyone has the idea what can be wrong?

 Below is my description of U-233 and the part of physics list for fission.

 Sincerely,

 Bari.

****************************************************************************
// U-233 

   G4Isotope* U233 = new G4Isotope("U233",Z=92, A=233, density=233.01*g/mole);
        
    G4Element* eU = new G4Element ("Uran_elem", "U", 1);

    eU-> AddIsotope(U233, 99.99*perCent);

    G4Material* Uran = new G4Material ("Uran_mat", 19 * g/cm3, 1);

    Uran -> AddElement(eU,1);

//fission process


G4HadronFissionProcess* neutronFission = new G4HadronFissionProcess();

G4ParaFissionModel* theParaFission = new G4ParaFissionModel();

G4NeutronHPFissionData* theHPFissionData = new G4NeutronHPFissionData();

neutronFission->RegisterMe(theParaFission);

neutronFission->AddDataSet(theHPFissionData);

pmanager->AddDiscreteProcess(neutronFission);
