摘要：

The average charge states of 0.1-1.5 MeV/u Fe, Co, Ni and Cu ions in solid Au and Bi targets have been determined, by estimating the mean numbers of outer-shell spectator vacancies during the K-vacancy decay. The latter quantities were obtained from the yield and energy shifts of the Kalpha, beta X-rays, by comparing with calculations in the independent electron approximation. The reported equilibrium charges, mostly characteristic for the inside of the target, are in fairly agreement with Nikolaev and Dmitriev semi-empirical formula [Phys. Lett. 28A (1968) 277].
