None Different Ionisation energy

Hello everyone,

I have a very simple question about material definition.

Why an ionisation energy is not the same if I am using different definitions:

 G4Element* elC  = new G4Element("Carbon"  ,"C" , z= 6., 12.01*g/mole);
 G4Element* elB  = new G4Element("Boron"  ,"B" , z= 5., 10.806*g/mole);
 Boron_Carbide = new G4Material("Boron_Carbide", 2.48 * g / cm3,2);
 Boron_Carbide->AddElement(elB, fractionmass = 0.78263);
 Boron_Carbide->AddElement(elC, fractionmass = 0.21737);

VS

 nistMan->FindOrBuildMaterial("G4_Boron_Carbide"); // Density is 2.52 * g / 
 cm3

For the first one, I get number - 77.1 Using the NIST this number is - 84.7, and also it's defined there manually.

Could you explain how is it happen?

Best regards,

Volodymyr
