A final state wave function of multiple scattering theory is followed in this study. The present outcomes are compared with those of hydrogenic ground state, 2P state and ground state experimental results. Obtained findings show a good qualitative agreement with existing results. %K Hydrogen %K Ionization %K Double Differential Cross-Section %K Metastable %K Scattering %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=125297
