Effects of additional electron vacancies on parameters of the radiative excitation

This work is aimed at demonstrating the influence which the formation of multiple-vacancy configurations has on deexcitation parameters of such a practical importance as the fluorescence yield. While in heavier systems the conception of an invariant atom core gives a good idea of K-hole filling processes the heavy-ion-induced X-ray emission from second- and third-row atoms attains a complexity which cannot even be comprehenced by a homogeneous scattering model of vacancy creation and decay. Of course, in most cases the environment was found to have a more pronounced effect on L-hole filling processes than on the corresponding K X-ray phenomena. However, apart from the enhanced complexity some other conditions exist which render its experimental detection a rather intricate task. (author)
