| The final charge state distributions of ions are calculated after photoionization 1s→∞ , 2s→∞ and resonant excitation 1s→3p and 2s →3p in neon atoms. The calculation of vacancy cascades based on the simulation of radiative and non-radiative pathways to fill the inner-shell hole and spectator vacancies in atomic configurations. The charged ions at 1s hole state after photoionization mainly turns into Ne2+ and Ne3+ ions. In the1s hole situation, the doubly charged Ne2+ following photoionization are predominate, while in 2s hole situation the singly charged Ne1+ ions are the most abundant one. At 2s hole state after photoionization and resonant excitation, the charged Ne1+ predominate in the distributions. The consideration of electron shake off processes improves the results of final charge state distribution. The results of charge state distributions of ions after core hole production agree well with the experimental values. 1. Introduction: | ||||
