Measurment of L X-Ray Production Cross-Sections and Li Subshell Florescence Yields

Abstract

Li (i=1, 2 and 3) X-ray production cross sections have been measured for 14 elements in the atomic number range 55≤Z≤81 at 15.73 keV. The values of Li subshell fluorescence yields (ω1, ω2 and ω3) have been determined using the presently measured X-ray production cross sections and the theoretical Li subshell photoionization cross sections values, Coster–Kronig transition probabilities and radiative emission rates. The measured X-ray production (XRP) cross-sections and fluorescence yield values were compared with the theoretical and semi empirical values, respectively
