✦ Synopsis

Measurements have been performed

using an x-ray tube with a secondary exciter system as the excitation source. The x-ray tube with a secondary target arrangement was used to obtain high intensity with high degree of monochromatization.

By using an x-ray tube it is possible to measure L x-ray fluorescence cross-sections even for low intensity x-rays (L,). Experimental results have been compared with theoretical values. A fairly good correspondence is observed between experimental and calculated values.
