A rigorous derivation of the characteristic fluorescence correction factor for use in electron probe microanalysis is presented. To achieve a high accuracy of the resulting expression Coster-Kronig transitions and effective fluorescence yields are taken into account and special attention is directed to the excitation conditions, e.g. the subshell structures. The integrations are carried out as accurately as possible, i.e. analytical solutions are employed if possible. Approximation and simplifications are avoided as far as possible.
