Abstract

Abstract: We use the Extended X-ray absorption fine structure (EXAFS) to measure the mass attenuation coefficient of Nb2 O5 Niobium compound in the X-ray energy range 18.9132 - 19.6882 keV. The results represent the most extensive experimental data set for Nb2 O5 and include absolute mass attenuation coefficients in the region of extended x-ray absorption fine structure. Comparison of the results with tabulations of calculated photo electric absorption coefficients indicate the differences between the calculated and observed values with the theoretical predictions.
