The authors advance and examine a new mechanism which strongly influences the photoionisation processes above the 4d threshold in Xe and Ba. It is shown that the elastic and inelastic scattering of the inner-shell photoelectron by the outer-shell electrons determines the rate of single and double ionisation, decomposing the cross section of the inner-shell photoabsorption into these two channels. The results of these calculations are in good agreement with experimental data.
