The Coster-Kronig transitions (f(12); f(23), and f(13)) are non-radiative transitions. The Coster-Kronig enhancement factors due to the effect of the Coster-Kronig transitions on L X-ray fluorescence cross-sections have been calculated theoretically. The calculated values have been compared with other earlier experimental and theoretical values.eninfo:eu-repo/semantics/openAccessArticle1306Q4Q312691272WOS:000396117800003
