High resolution Cn L3,2-edge XANES have been obtained for Ca metal and a series of Cu-Au alloys (Cu3-Au, CuAu and. CuAu3). It was found that the Cu L3-edge XAMES for all the samples under investigation exhibit the characteristic three-peak resonances predicted by theory. The Cu L3-edge XANES shows some interesting systematics which can be correlated to charge redistribution in Ca-Au alloys.
