Extended Fine Structure of Copper K-Absorption Discontinuity in the Metal and in its Alloy with Antimony

Abstract

The extended fine structure associated with the K-absorption discontinuity of copper in pure metal and in the alloy Cu_82.5Sb_17.5 is studied using a 40 cm Cauchois type bent crystal X-ray spectrograph. The extended fine structure has been explained on the basis of the theory proposed by Lytle, Sayers and Stern. The theory has also been used to determine the bond length for the alloy. Levy’s method has also been used to determine bond lengths for the systems under study. The results obtained from both the theories have been compared.
