| Abstract: | The theory of the shapes of Auger decay lines of satellite two-hole-one particle states accompanying photoionization based
on the Green's function method is developed. The lineshapes of Auger decay of satellite states 2

) in valence p-photoelectron spectra of Ne and Ar atoms are calculated (hole states are indicated by square brackets throughout). It is
shown that in some cases the Auger lineshapes reproduce the shape of the photoelectron satellite line, but in other cases
Auger line may be narrower then the photoelectron line and may have opposite direction of asymmetry. The theoretical results
are in agreement with experimental low-energy Auger spectra.
