Energies and widths of atomic core-levels in liquid mercury

“…The same trend is observed for the transitions involving M 1 holes, whereas for L 2 and L 3 transitions involving M 4,5 vacancies in the final states, a satisfactory agreement is found. This observation that theory overestimates the transition widths when 2s [38] or 3s [64] vacancies are present in the initial or final state results from the difficulty of calculations to provide reliable predictions for the Coster-Kronig rates. In general, the latter are indeed overestimated by theory.…”

“…The intensities, energies, Lorentzian widths, Gaussian standard deviations, and the two parameters of the linear background were let free in the fitting procedure. The weighted average of the five Gaussian standard deviations obtained from the fits was found to be σ ϑ = 4.83(28) arcsec, which corresponds for the L 1 M 2 and L 1 M 3 transitions to instrumental energy broadenings σ E of 1.29(7) and 1.39(8) eV for 81 Tl, 1.46(8) and 1.59(9) eV for 83 Bi, and 3.00 (17) [1]. To further check the goodness of the instrumental resolution measurements, the Kα 1 line of Au used for the determination of the constant d 110 was refitted with a Voigt profile, letting free in the fitting procedure all parameters except the Gaussian instrumental broadening which was kept fixed at the value of 8.64 eV corresponding for this transition to the above-mentioned angular resolution.…”

“…In the present project, the M satellites of the L 3 N 4,5 transitions were observed for almost all studied elements, whereas those These asymmetries, which result from the angular momentum coupling between the L 2 core vacancy and the partially filled outer shells, were accounted for in the fits by adding one or two additional Voigt functions. For Yb ([Xe]4f 14 6s 2 ), no asymmetry was observed since in the Yb crystal the two 6s electrons participate in the crystal bonding, leaving the atom with a closed electronic shell configuration [17]. The same holds for Tl ([Hg]6p) and Bi ([Hg]6p 3 ) which are generally monovalent and trivalent, respectively.…”

X-ray resonant Raman scattering from noble gas atoms and beyond

“…Since the energy width of L 3 hole is 2.62 eV [16] and the experimental energy resolution was about 1.0 eV, the RIXS line narrowing was substantial and allowed to detect directly for the first time the transition to [2p 3/2 ]6s state (Fig. 3).…”
