Analysis ofKα line emission from aluminum plasmas created by intense proton beams

Excited spectator electron effects on spectral line shapes

“…Finally, earlier work [27][28][29][30][31][32] investigated Stark broadening profiles and line-intensity ratios of dielectronic satellite lines. These studies, however, only included level widths but neglected the interference terms.…”

“…11 for plasma conditions expected in € Kα line emission experiments. [31] Interestingly, the interference effects at the higher densities lead to significant line narrowing. The effect of the ion microfields is displayed in Fig.…”

“…Earlier work [27][28][29][30][31][32] Area normalized profiles, which neglect the ion broadening, are plotted in Fig. 11 for plasma conditions expected in € Kα line emission experiments.…”

Diagnostics of warm dense matter by high-resolution X-ray spectroscopy of hollow ions

“…It means that such plasma hollow ions will be created independently on the ion pulse duration (see for example, Moribayashi et al, 2001a). The ion energy for effective ionization of inner atom electrons must be higher than the energy of fast electrons, of course, but the experiments, carried out at the different accelerators, showed that energy of nowadays used heavy projectile ions are enough for ionization of the K-electrons in the different atoms (see, for example, MacFarlane et al, 1993;Rosmej et al, 2002;Rosmej, O. et al, 2003;2005b;2005a;Pikuz et al, 2006;Rzadkiewicz et al, 2010;Kawamura et al, 2011;McMahon et al, 2011;Nakano et al, 2012).…”

“…It should be noted that KL-hollow ions (ions with one hole in the K-shell and one hole in the L-shell) have been observed in aluminum plasma heated by intensive proton beam (Bailey et al, 1990). In the papers by Wang et al (1993) and MacFarlane et al (1993) it was shown that K α satellite lines of aluminum ions observed by Bailey et al (1990) 3l. The second group is just KL-hollow ion configurations.…”
