Calculation the Effective atomic number , electron density, Half value layer and mean free path of Iron, Copper and Silver

Abstract

Effective atomic number (Zeff) ,electron densities (Nel) , half value layer(HVL) and mean free path (mfp) has been determined with the help of semi-empirical relations for Iron, Copper and Silver at energy range 0.36 to 1.33MeV .The study proved the coincidence of the experimental and theoretical values of effective atomic number while the electron densities and mean free path are found nearly remain constant as a function of energy.
