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

Effective Atomic Numbers of Glass Samples
International Journal of Computational and Experimental Science and EngineeringEffective atomic numbers are a term used to understand the interaction of a compound or material with radiation. In particular, this term is often used for materials with complex structures that can be expressed by a single fixed atomic number. If different elements in a material are present in different concentrations, the effective atomic number of ...
