“…The spin-polarization tends to be mostly positive, with values reaching 100% at frequencies somewhat before the maxima of the broad resonances. Note that our results around the 9s and 7d agree rather well with previous theory and experiment [11]. The maximum of the spin-polarization (100%), occurring approximately at the minimum of the cross-section before the resonances nd, is reminiscent of the Fano effect in Cs, with some significant differences.…”

We present theoretical results on the spin-polarization of photoelectrons ejected in the process of single-, two-, and three-photon ionization of xenon by circularly polarized radiation. In all cases, we find significant spin-polarization at a series of photon frequency ranges together with substantial cross-sections. The results are analysed and discussed from the perspective of spin-polarized electron sources for which they seem rather promising.

“…2) [13]. Much better resolved ARS lineshape data for the rare gases Ar, Kr and Xe [1,14,15] were obtained and later complemented by coherent vacuum-ultraviolet (VUV) excitation spectra [16][17][18][19][20][21][22]. The development of excimer lasers containing raregas atoms [23] further stimulated experimental and theoretical work to characterize in detail the photoionization process involving rare-gas atoms, in particular from excited levels.…”

A review of experimental and theoretical studies of the threshold photoionization of the heavier rare-gas atoms is presented, with particular emphasis on the autoionization resonances in the spectral region between the lowest two ionization thresholds (mp 5 2 P 3/2 and mp 5 2 P 1/2 , with m = 2, 3, 4, and 5 for Ne, Ar, Kr, and Xe, respectively). Observed trends in the positions, widths, and shapes of the autoionization resonances in dependence of the atomic number, the principal quantum number n, the orbital angular momentum quantum number and further quantum numbers such as K, J and F specifying the fine-and hyperfine-structure levels, are summarized and discussed in the light of ab initio and multichannel quantum defect theory calculations. The dependence of the photoionization spectra on the initially prepared neutral state, e.g. the 1 S 0 ground state, the mp 5 (m + 1)s 3 P 2 and mp 5 (m + 1)s 3 P 0 metastable levels and other states prepared from the ground or metastable levels in single-and multiphoton processes, are also discussed, including results on the photoionization of aligned and oriented samples and on photoelectron angular distributions. The effects of various approximations in the theoretical treatment of photoionization in these systems are analysed. The very large and at first sight discouraging diversity of observed phenomena and the numerous anomalies in spectral structures associated with the threshold ionization of the rare-gas atoms can be described in terms of a limited set of interactions and dynamical processes. Examples are provided illustrating characteristic aspects of the photoionization, and sets of recommended parameters describing the energy-level structure and photoionization dynamics of the rare-gas atoms are presented which were extracted in a critical analysis of the very large body of experimental and theoretical data available on these systems in the literature.

“…Previous spectroscopic work on the Rydberg states in Xe below the 5p 5 3/2 or 5p 5 1/2 thresholds, as accessed from the Xe 5p 6 1 S 0 ground state, includes one-photon excitation of the odd parity ns J = 1 and nd J = 1 states [2,20,[25][26][27][28][29][30][31][32] and multiphoton excitation of odd or even Rydberg states by non-resonant [19,[33][34][35][36][37] or resonant [38,39] multiphoton excitation. In addition, single-photon [40][41][42][43][44][45][46] or resonant as well as non-resonant two-photon [8,[47][48][49][50] excitation from either of the two metastable levels of Xe have been exploited to investigate even and odd Rydberg states, respectively.…”
