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 ,
and
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.
