    The interatomic Auger transitions in compounds containing atomic components with core levels close in energy are studied theoretically and experimentally. The Coulomb transitions of a hole between such levels lead to a resonant enhancement of the Auger spectra (with respect to the energy difference between the levels). Interatomic Auger transitions involving high lying levels are formed by shaking up electrons due to the dynamic field of photo holes produced during the transition. These effects are observed experimentally in XPS and Auger spectra of CuInSe2 type materials. The experimental XPS spectra in CuInSe2 based compounds show intense interatomic CuL3M2,3InN4,5 and CuL3InN4,5V Auger transitions. The interaction of copper 3p and indium 4p levels of similar energy gives a resonant increase in the magnitude of the first Auger transition. Shaking the In 4d electron because of the appearance of a photo hole is the mechanism of the second transition.
