Auger cascades in atoms and ions of astrophysically important elements

The Monte-Carlo method has been used to simulate Auger cascades in atoms and ions of Mg, Al, Si, S, Ar, Ca, Fe with account for the radiative and Auger transitions. The probabilities of ejection of various numbers of electrons after the initial creation of vacancy in different shells have been calculated. Corresponding probabilities for atoms and ions of C, N, O, Ne (where single Auger transitions are possible) are presented. The data on radiative and Auger transition rates available in the literature for all the above-mentioned atoms and ions are collected and discussed.
