27. An analogous shell-structure analysis was presented in Ref. in the absence of final-state effects.
28. We speculate that the free-atom peak is more sensitive to saturation effects. This may explain the reduction of the peak height in Fig. and also lead to the up-shift of the peak in Fig..
29. See Supplemental Material at http://link.aps.org/supplemental/10.1103/ PhysRevA.84.011608, which presents a detailed comparison between theory and experimental data at high temperatures and a discussion of the high-frequency tail of the rf spectra.
