The average 2p (L_2,3) subshells fluorescence yield (_2,3) in 11 elements with Z ranging from 60 to 90 were measured with corporation of total L_2,3 X-ray production cross-sections. Measurements were carried out exciting L₂ and L₃ subshells of relevant elements that were exposed to beam of selected K X-rays from secondary sources. The measured values were compared with theoretical and semi-empirical values. It is clear that the present values of experimental _2,3 are generally smaller than the calculated and semi-empirical values for some elements in the atomic number range 60–90.
