I am trying to implement 238U converter for the fission of neutrons, in my
geant4 code.

I tried to define, the 238U  as given below, (took these sample code lines
from GEANT4 sample codes).

//////////////
// *define an Element from isotopes, by relative abundance
*////////////////
G4Isotope* U5 = new G4Isotope(name="U235", iz=92, n=235, a=235.01*g/mole);
*G4Isotope* U8 = new G4Isotope(name="U238", iz=92, n=238, a=238.03*g/mole);*
G4Element* elU  = new G4Element(name="enriched Uranium", symbol="U",
ncomponents=2);
elU->AddIsotope(U5, abundance= 90.*perCent);
elU->AddIsotope(U8, abundance= 10.*perCent);

I defined the U238 converter as below;

//single- gap Detector With U238 converter
G4Material* meterial[ ] ={Al, U238, Butane,Al};

// Single-gap Detector converter
G4double halfz[ ] ={2*mm, 0.5*mm,  2*mm,  2*mm};


If I define the Uranium 238, like above lines from GEANT4 Sample code.

*I get error in the code. *

Could you please guide me in defining the 238U, and implementing.

Further could you please guide me, which GEANT4 Physics list will be
suitable for
neutron fission evaluation?

either I can utilize,  QGSP_BERT_HP , QGSP_BIC_HP, LHEP, emLivermore?

I will appreciate your help in this regard.


With best wishes,
