Strong resonance L-absorption of sulphur fluorine molecule

Parameter-free calculations of X-ray spectra with FEFF9

“…Here we describe the advances, which are applicable to all spectroscopies involving electronic excitation, including among others X-ray absorption spectroscopy (XAS), 2 X-ray Raman scattering (XRS), also known as non-resonant inelastic X-ray scattering (NRIXS), 9 and electron energy-loss spectroscopy (EELS). [10][11][12][13] Our implementation of these developments is based on the real-space Green's function (RSGF) approach 2 within the quasiparticle picture, and differs from all earlier approaches [14][15][16][17][18] in the treatment of several many-body effects. The RSGF approach has been widely applied, especially for extended X-ray absorption fine structure (EXAFS) and X-ray absorption near edge spectra (XANES).…”

Resonance effects on the inner-valence levels of SF6 in the photon-energy range 52–72 eV

“…It showed that there is a resonant enhancement of both the S 2p main line and satellite at the same photon energy. The resonant feature at this energy had been assigned previously as the S 2 P (2t 1u }-->e g shape resonance (196.5 eV) (6)(7)(8)(9). We note that despite the unusual behavior of the e g shape resonance in S 2p…”

“…For these and other reasons, a large amount of information has been generated on SF 6 photoionization and related excitation processes: On the theoretical side, several groups have calculated the electronic structure ( Gianturco et al 1971, Connolly and Johnson 1971, von Niessen et al 1975, Hay 1977, von Niessen et al 1979 of SF 6 , and others have calculated partial photoionization cross sections (Gianturco et al 1972, Sachenko et al 1974, Levinson et al 1979 and photoelectron angular distributions for all the subshells of SF 6 • In addition, the elastic e-SF 6 scattering cross section (Dehmer et al 1978, Benedict andGyemant 1978) has been calculated indicating the role of the above-mentioned shape resonances and the close connection (Dehmer and Dill 1979a) between shape resonances in electron scattering and photoionization contexts. An even larger collection of experimental work includes: (i) X-ray absorption and emission cross sections from core levels (LaVilla and Deslattes 1966, Zimkina and Fomichev 1966, Zimkina and Vinogradov 1971, Blechschmidt et al 1972, LaVilla 1972, Agren et al 1978, (ii) VUV absorption by valence levels (Nakamura et al 1971, Blechschmidt et al 1972, Sasanuma et al 1978, Codling 1966, Lee et al 1977, (iii) photoelectron spectra using X-rays (Gelius 1974) and VUV resonance lines (Gustafsson 1978, Gelius 1974, Potts et al 1970, Sell and Kuppermann 1978, (iv) photoelectron angular distributions with He I radiation (Sell and Kuppermann 1978), (v) partial photoionization cross sections (Gustafsson 1978, Ferrett et al 1986) and photoelectron angular distributions , Ferrett et al 1986) using synchrotron radiation, (vi) pho...…”
