Question Material definition

I am trying to simulate a neutron shield made of Lithium Polyethelene.

When I use pure Polyethelene; the neutrons interact with the material but once adding the Lithium; something goes wrong and all neutrons just pass with no interaction at all.

Is there anything wrong with the way I defined it?

G4Isotope* isLi6 = new G4Isotope("Li6", z=3,6.015*g/mole );
G4Isotope* isLi7 = new G4Isotope("Li7", z=3, 7.016*g/mole);

G4Element* NaturalLi= new G4Element("NaturalLi", symbol="Li",2);

NaturalLi->AddIsotope(isLi6, 7.5*perCent); NaturalLi->AddIsotope(isLi7, 92.5*perCent);

G4Material* Lii=new G4Material("Lii",0.534*g/cm3,1); Lii->AddElement(NaturalLi,1);

G4Material* C2H4= new G4Material("C2H4",0.94*g/cm3,2); C2H4->AddElement(C,2); C2H4->AddElement(H,4);

G4Material* SHIELD = new G4Material("SHIELD",1.06*g/cm3,2); SHIELD->AddMaterial(C2H4, 92.44*perCent); SHIELD->AddMaterial(Lii, 7.56*perCent);

Thank you very much
