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);
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?
