Interpretation of the N2,3N4,5O2,3 Coster–Kronig spectrum of xenon

Experimental Verification of Quadrupole-Dipole Interference in Spin-Resolved Photoionization

“…Interaction with double excitations of the 4d subshell causes the 4p "1=2" ÿ1 peak to completely disappear and the 4p "3=2" ÿ1 peak to be asymmetrically smeared out [18]. An assignment of the studied photoline to 4p "3=2" ÿ1 is supported by our measurement of the transferred spin polarization component P transf , presented in Fig.…”

4d -inner-shell ionization of Xe+ ions and subsequent Auger decay

“…Note that theoretical curves have been shifted by +2 eV to match the positions expected from Ref. [25] (vertical bars).…”

“…This is in disagreement with Gottwald et al who instead report on three broad structures at 72.2, 74.9, and 76.2 eV, that is, in a region where we do not detect any photoelectron signal within our error bars. The expected energy positions of the Xe 2+ 4d −1 5p −1 states which are populated upon 4d shell ionization of Xe + (5p −1 ) states can be deduced from the literature, namely, from the measurement by Kivimäki et al [25] of the "4p" photoelectron spectrum of the Xe atom and of the associated "N 3 " N 4,5 O 2,3 Coster-Kronig decay to these Xe 2+ 4d −1 5p −1 states. They are summarized in Table I using the binding-energy scale relative to the ground state of the Xe atom.…”

“…[4] at hv = 103.3 eV (a, top). The broad blue and thin red vertical bars indicate the expected energy positions for the Xe + 5p −1 ( 2 P 3/2 ) → Xe 2+ 4d −1 5p −1 and the Xe + 5p −1 ( 2 P 1/2 ) → Xe 2+ 4d −1 5p −1 transitions, respectively; the transition energies are estimated using the 4d −1 5p −1 binding energies of Kivimäki et al [25]. The blue (solid) and red (dotted) curves in the bottom graph (c) show the calculated Xe + ( 2 P 3/2 ) → Xe 2+ 4d −1 5p −1 and Xe + ( 2 P 1/2 ) → Xe 2+ 4d −1 5p −1 photoelectron spectra, respectively.…”

“…The present experimental values (first column) are compared to the 4p Auger experiment by Kivimäki et al [25] and to the threshold electron coincidence experiment by Bolognesi et al [29]. Fig.…”
