Abstract :
The mixing of the excited states of an atom with the ionization continuum is considered by a modification of Fano\´s theory of autoionization. It is shown that in the case of the noble gases this leads to a reduction of the threshold power-law index 
from 
to 
(where 
is the ionization energy, En the lowest excited state energy, and 
the photon energy) as found experimentally.
from to (where is the ionization energy, E the photon energy) as found experimentally.Keywords :
