Abstract
Cu K-edge EXAFS measurements have been done for NaCl : Cu+ in order to study the lattice relaxation around a cuprous ion. It was found that the bond length of Cu+ and Cl- in NaCl takes almost the same value as that of CuCl crystal. This suggests a very large distortion of the latice around a cuprous ion.
