Some cascades of Auger and radiative transitions following inner-shell ionisation have been simulated using the Monte Carlo method and taking the energy of transitions from the relativistic Hartree-Fock-Pauli approximation. It has been found that the configurations, in which all Auger transitions are energy forbidden, play an essential role in the cascade development. This energy prohibition and a more correct estimation of several-electron shake-off improves the agreement of theory with the experiments on ion charge distribution. The calculated Auger electron and X-ray spectra are presented.
