Popis: Some photonic energy absorption parameters such as the mass attenuation coefficient μ t , the molecular σ M , atomic σ A , the electronic cross-sections σ E , the effective atomic number Z eff and the electron density N E have been calculated and measured. We have gained the terms jump factor of effective atomic number JZ eff and jump factor of electronic density JN E to literature with the help of these fundamental parameters. Also, we want to obtain both XAFS effect and the applicability of mixture rule. The most interesting finding in this study is that the trend of the total molecular, atomic and electronic cross-sections is getting beyond the measure by the absorption edge and these cross-sections are affected in the region of absorption edge. The obtained results have been compared with some other theoretical values given earlier.
