Experimental determination of L-subshells x-ray yields and production cross sections of thick lead (Z=82) element by impact of 15–30 keV electrons

Abstract

We present experimental results on the impact energy dependence of L-subshell x-ray yields and production cross sections for the thick lead target (Pb, Z = 82) under impact of 15–30 keV electrons. Results are compared with the simulation data from the Monte Carlo Penelope code with the Distorted Wave Born Approximation (DWBA) formulations. The comparison yields fairly good agreement for the L-shell x-ray yields within the experimental uncertainties. Furthermore, the present results of the intensity ratio of $L_{\beta },L_{\gamma }$ and $L_l$ lines to the intensity of $L_{\alpha }$ and their corresponding x-ray production cross sections are compared with available experimental and theoretical data; the agreement is found to be satisfactory. X-ray production cross sections for L-shell x-rays are derived by employing the thick target method (An et al., 2006). Furthermore, we have presented for the first time the experimental results on yield and x-ray production cross sections of the $L_l$ line and have compared the results with the simulation data; the agreement between two results is found to be good within the error bars of the measurements.
