Proton-induced L-shell X-ray production cross sections and their ratios

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

“…For impinging protons, our data are in good overall agreement with earlier measurements on Pb; they are higher than the ones of Braziewicz et al (1984a) in the overlapping energy regions for Pt and Bi and agree well with the more recent measurements of Padhi et al (1994) on Pb and Bi. For impinging 4 He ions, our data are in good agreement with those of Jesus et al (1985) on Pb, large for the L α line, while they are higher than those of Braziewicz et al (1984b) on Pt and Bi.…”

“…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. Thus we prefer to adopt Krause's basis, that has been more widely used, and in particular has been used by the majority of the authors who have reported data on the elements investigated here (Barros Leite et al 1977, Cohen 1980, 1981and 1984b, Bhattacharya et al 1982, Braziewicz et al 1984aand 1984b, Budnar et al 1984, Jesus et al 1985, Moheb et al 1985, Szökefalvi-Nagy et al 1993.…”

“…We have arranged in a unique analysis our own results and the ionization cross sections from other laboratories reported in tabular form (Bhattacharya et al 1982, Budnar et al 1984, Cohen 1980, 1981and 1984a, Moheb et al 1985, Perillo et al 1996, Semaniak et al 1992, Szökefalvi-Nagy et al 1993. The values of Moheb et al (1985) have been used only in the energy range 0.36-0.44 MeV and recalculated to subtract the L γ 6,8 contribution from their quoted L γ 2,3 yields.…”

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

“…Most of the experimental data for L α and L total x-ray production cross sections published so far can be found in the compilation by Sokhi and Crumpton (1984) and in the recent compilation by Orlić et al (1994a). For L α x-ray production cross sections experimental data are available for Ag in the proton energy range between 0.25 and 1.75 MeV (Sarter et al 1981, Jesus et al 1986, 0953-4075/96/102021+11$19.50 c 1996 IOP Publishing Ltd for Cd in the proton energy range between 0.25 and 0.4 MeV (Sarter et al 1981), and for Sb in the proton energy range between 0.5 and 3.2 MeV (Jesus et al 1986, Braziewicz et al 1984. Rosato et al (1986) reported only L-shell ionization cross sections in graphical form for Ag and I for proton energies between 0.3 and 5 MeV.…”
