Cross sections of cascade production of photoions after photoionization of the silver atom in the 0.07–100 keV incident photon energy range

Abstract

The formation of multiply charged Agq+ ions resulting from photoionization and subsequent cascade decay of inner-shell vacancy states is studied using the method of construction and analysis of the cascade decay trees. Cross sections for the cascade production of Agq+ ions, yields of Agq+ ions, and mean photoion charge are calculated as functions of incident photon energy in the range of 70 eV to 100 keV. The results of this study are relevant for developing the strategies of radiotherapy using Ag-based radiosensitizers.
