L-shell x-ray production for Rh, Ag, Cd, Sb and I with protons in the energy range from 1.6 to 5.2 MeV

Abstract

Individual , , , and x-ray production cross sections for the elements Rh, Ag, Cd, Sb and I have been measured by protons in the energy range 1.6 to 5.2 MeV. The experimental results for x-ray production cross sections and cross section ratios are compared with the RPWBA - BC theoretical predictions and with the other available experimental data. The influence of using different databases for atomic parameters in the conversion of theoretical L-shell ionization cross sections to the L-shell x-ray production cross sections is discussed.

Proton- and4He-ion-induced L-shell ionization of Pt, Pb and Bi

“…Recently, some authors (Braziewicz et al 1991, Bogdanovic and Fazinic 1996, Amirabadi et al 1997 tried to use ω i and f ij values taken from the compilation of Chen et al (1981), indicating a better agreement with the experiment than with Krause's data. However, no very significant differences arose, giving clear evidence about the better basis to be used and the recent results of Yu et al (1997) give evidence in the opposite direction.…”

Updated database for L x‐ray production by protons and extraction of L‐subshell ionization cross sections from only Lγ and Lα + Lβ cross sections

“…The database used for this study originates with the data compiled in in Refs 1–3. With additional references 4–8 that were not cited in these compilations and the subsequently published data,9–32 a total of 29 papers was found, including several that presented the results only in graphical form 4–8. The graphs from these papers were digitized and the values extracted in tabular form, although a higher uncertainty in these values should be expected.…”
