Measurements of L-subshell x-ray production cross sections and M-shell x- ray yields of Pb by low-energy electron impact using the thick-target method

摘要

The Lα, Lβ, and Lγ x-ray production cross sections and M-shell x-ray yields by 5-29 keV electrons bombarding a thick Pb target were measured. The effects of multiple-scattered electrons, from the bremsstrahlung and other secondary particles within the thick sample were corrected using the Monte Carlo simulations. The experimental results are compared with the DWBA predictions of Bote et al., and also with the experimental data from the literature. The results indicate that the measurements of the production cross sections for the L subshells of the elements with higher atomic numbers using the thick-target method are feasible and reliable.
