摘要
The average 2p (L(2,3)) subshells fluorescence yield (pi(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 L(2) and L(3) 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 pi(2,3) are generally smaller than the calculated and semi-empirical values for some elements in the atomic number range 60-90.
