We use multichannel resonant scattering theory for an extension of the
conventional theory of autoionization resonances in photoabsorption.
it incorporates autoionization induced by resonance fluorescence. As a
result we obtain a modified Fano profile formula. The result shows th
at the new mechanism has in certain cases a strong influence on the sh
ape of the resonances.
