Abstract

The effective atomic number ( $ Z_{\backslashrm eff}$Zeff is a quantity which gives the fraction of the total number of electrons in a composite material participating in the photon-atom interaction. The effective atomic number has been determined for the materials of known composition by using different methods. However, no method has been reported so far to determine $ Z_{\backslashrm eff}$Zeff for thick samples of unknown composition. In view of this, we have evolved a simple method to determine the effective atomic number, which uses the scattering intensity ratios measured at two scattering angles, in which a sample of known $ Z_{\backslashrm eff}$Zeff or Z is taken as a reference sample. The values of $ Z_{\backslashrm eff}$Zeff obtained by this method agree with those obtained from the Auto-Zeff software within the stated errors. This method could be helpful in determining the effective atomic number of samples of unknown composition.
