Transmission of X-rays Fluorescence through Vanadium,Chromium and Managanese

In this paper , the measurements of x-ray fluorescence emitted from different metallic surfaces which have been excited by two distinguished lines Cu-kal and Cu-kpi . are reported . The transmission has been studied by three filters (Vanadium , Chromium and Manganese ) . The transmission curves reveal a kink near the center . This kink is explained as due to the absorption edge of the cobalt
