Hi all I have a question for XANES of Zinc compounds. It is known that the pre-edge for Zinc k-edge generally doesnt exist because 3d state of Zinc atom is occupied. However, I got it from ZnMgO with wurtzite structure. 4 oxygen in first shell and 12 zinc in second shell are located around Absorbing atom, Zinc in wurtzite structure. And then I know that some Mg atoms are replaced on zinc site from EXAFS. I wonder the reason for the appearence of pre-edge. Is it structural problem? or substituted Mg? If anybody know reference papers for pre-edge of zinc K-edge, Please answer me. _________________________________________________________________ 새로운 Windows 7: 여러분에게 맞는 최상의 PC를 찾으세요. 자세히 보기. http://windows.microsoft.com/shop
There was a paper by J. Penner-Hahn et al. studying ZnCl2 by EXAFS and using it to demonstrate the quadrupole (1s-3d) transition by analyzing angular dependence of pre-edge features of Zn K-edge. You may contact him directly for exact reference.

Thank Anatoly. Do you know J.penner-Hahn's e-mail or exact reference name? I cant find his paper in search site.
