L X-ray production cross-sections for 12 elements were measured at 5.96 keV excitation energy in the atomic number range 40 less than or equal to Z less than or equal to 55. The average L shell fluorescence yields of these elements have been evaluated by using the presently measured cross-section values and the theoretical L shell photo-ionisation cross-section values at the same energy. The average M shell fluorescence yields were evaluated using the line widths of L X-ray and level widths of L and M shells.
