Determination of the effective atomic number: A theoretical justification
EPL (Europhysics Letters), 2018 In this paper, we have tried to seek a theoretical justification for the effective atomic number for Compton scattering studies by computing it from free atom Hartree-Fock wave function based Compton profiles compiled by Biggs et al. Typical experimental examples have been provided which show a good agreement with that of theory justifying the validity
