TL;DR: In this paper, the photon-ion merged-beam technique was used at a synchrotron light source to measure the absolute photoionization cross sections of Xe3+, Xe4+ and Xe5+ ions.

TL;DR: Baral et al. as mentioned in this paper reported cross-section measurements for single and double photoionization of C60+ ions in the photon energy range 18-150 eV accompanied by the loss of zero to seven pairs of carbon atoms, as well as for fragmentation without ionization resulting in loss of two to eight pairs of C atoms.

TL;DR: In this article, the cross-beams of Snq + ions in charge states q = 4−13 with 4d[10 − (q − 4)] outer shell configurations have been studied in the energy range from the corresponding thresholds up to 1000 eV. Contributions of different ionization mechanisms have been analysed by comparing the experimental data with calculations employing the configuration-averaged distorted wave approximation.

TL;DR: In this article, the relative importance of indirect processes involving inner-shell excitation with subsequent autoionization was identified, revealing that an ≈1% fraction of metastable ions present in the parent Xe10 + ion beam has been analysed.
