Yields of multiply charged ions in cascading decays of hollow argon and krypton with two initial vacancies in their K and/or L shells

The yields of multiply charged ions produced by the cascading decay of doubly-inner-shell-ionized argon and krypton atoms are calculated via straightforward construction of de-excitation trees. The final-ion-charge spectra are found to be sensitive to the distribution of initial vacancies within K and L shells.
