Abstract
We have observed the coherence between the photoionization of two diff erent inner-shell vacancy states of argon, the energies of which diffe r by more than 75 eV. The method is based on the occurrence of interfe rences between the photo- and Auger electrons resulting from the photo ionization and subsequent Auger decay of the two states concerned. The measured line profile of the interference structure can be well expla ined using the theory of van den Brink et al. on state-state interfere nces.
