The samples were excited 59.537 keV photons emitted from an ²⁴¹Am radioisotope source with 100 mCi activity. These cross-sections also have been calculated theoretically by using atomic parameters. Relative intensity ratios of L X-rays have determined by using these cross-sections both experimentally and theoretically. Our experimental relative intensity ratios of L X-rays have compared the experimental values available in the literature.
