Photon interaction measurements of certain compounds in the energy range 30–660 keV

Abstract

The total photon interaction cross sections at six energies in the energy range 30–660 keV are determined in ten compounds, (NaNO3, KNO3, Sr(NO3)2, NaCl, SrCl2∙6H2O, BaCl2∙2H2O, NaClO3, (NH4)2SO4, MgSO4∙7H2O, and K2SO4) using a NaI(Tl) scintillation spectrometer in a good geometry setup. Analysis of the experimental data in terms of cross sections and effective atomic numbers is presented.

Measurement of absorption edge parameters near K edge for the compounds of Zn, Zr, Cd, Ba and Pb

“…The effective atomic number (Z eff ) are calculated [26,[40][41][42][43][44] as the ratio of effective atomic cross-section a σ to effective electronic cross-section el σ i.e. el a eff Z σ σ = (9) In order to calculate the eff Z of a materials, the measurements of a σ and el σ parameters are required.…”
