Total and K-shell photoeffect cross sections at K-edges of Cu, Zr, Ag, Sn, Ta, Au, and Pb

Abstract

Total attenuation cross sections, total and K-shell photoeffect cross sections, K-jump ratios, and total to K-shell photoeffect cross section ratios at the K-edges of the elements copper, zirconium, silver, tin, tantalum, gold, and lead are extracted from our earlier studies on total attenuation cross sections on these elements. These are compared with the latest and extensively tabulated theoretical photoeffect cross sections of Scofield and agreement within experimental uncertainty is observed. Further, empirical relations for K-edge cross sections and ratios are obtained, and the values of constants in these relations are tabulated. These empirical relations are found to reproduce the values to an accuracy better than one percent.
