Hi Gunter,

Thank you for the comment. I have add the material for Deuterium Gas as follows:

// Deuterium Gas ( with pressure 7.0 atm and room temp 293.15K)

 G4Isotope* iso_H2= new G4Isotope(name="D",iz=1,n=1,a=2.014*g/mole);
 G4Element* ele_H2= new G4Element(name="Deuterium Gas",symbol="D",
                                ncomponents=1);
 ele_H2 -> AddIsotope(iso_H2, abundance =100.*perCent);
 DeuteriumGas = new G4Material("Deuterium Gas",density= 0.00124*g/cm3,
                  ncomponents=1,kStateGas, 293.15*kelvin, 7.0*atmosphere);
 DeuteriumGas->AddElement(ele_H2,fractionmass =1);

Definition of Gas looks OK to me according the tutorial.
But Still I can not see neutron. My output for 20 MeV deuteron on D,
 still looks like follows.

If I change material name (i.e. to air ), I can see neutron.

Do I miss something in my material definition? or what is wrong?

Thank you,

Gin
