Abstract :The average number of ejected electrons and the probability of ion charge state distributions following K-shell ionization in atoms from Z = 10 to Z = 80 were calculated. Monte Carlo simulation technique was used to simulate all possible pathways of radiative and non-radiative transitions to fill the inner-shell ionization in excited atoms. The radiative and non-radiative branching ratios were calculated from Multiconfiguration Dirac-Fock insert ignore into journalissuearticles values(MCDF); and Dirac-Fock-Slater insert ignore into journalissuearticles values(DFS); wave functions. The average number of ejected electrons in atoms with Z = 10 is about two, because the non-radiative transitions exceed radiative transitions by 98%. The mean number of ejected electrons increases with atomic number Z. The results of ion charge state distributions and mean ejected number agree well with available experimental values.
