Fig. 15. Angle-integrated photoelectron energy distribution curves of uranium in the region of the giant 5 d -> 5 f resonance (90 eV < hv < 108 eV). The 5 f intensity at Ep is suppressed by more than a factor of 30 at the 5 ds/2 threshold (see the spectra for hv = 92 and 94 eV) and resonantly enhanced above threshold (see, e.g., the spectrum for hv = 99 e V). At an initial energy 2.3eV below Ep a new satellite structure is observed which is resonantly enhanced at the 5 d5/2 and 5 ds onsets. At threshold the satellite coincides with the Auger electron spectrum, which moves to apparently larger initial energies with increasing photon energy (from Ref. 67)...

The decay widths are in meV, citations are given in square brackets. Experimental value for ammonia is lacking because of the vibrational broadening in the Auger electron spectrum of ammonia [65], See Ref. [44] for the details of the Fano-ADC computation.

The boron Auger electron spectrum of BjOj shows peaks that can be assigned as KL L and AX2,3 2,3, with energies and widths consistent with those seen in the x-ray photoelectron spectrum, but it also shows several additional features associated with solid-state processes. The resolution of the Auger spectrum is insufficient to resolve contributions from individual molecular orbitals.

FIGURE 14. Normal (denoted by N) and resonant Auger spectra of LiF. Inset shows the total electron yield spectrum of LiF at the F K edge. Labels a-e indicate the mean photon energies where the electron spectra were recorded. The normal Auger electron spectrum was taken at hv = 800 eV. (by Aksela et al. in Phys. Rev.

As such, it competes directly with X-ray fluorescence (XRF) but it is not limited by the dipole operator selection rules. All energetically allowed transitions are observed in an Auger electron spectrum. In addition, the electron escape depth is also a few tens of angstroms, unlike XRF where typical escape depths are on the order of tens of thousands of angstroms.

The bombardment of gaseous PH3 by H+ ions (0.4 to 2.0 MeV) and HJ ions (0.4 to 1.2 MeV) was used to measure the L-shell Auger electron spectrum of phosphorus and to calculate the ionization cross section of the L-shell from the Auger electron yields [32].
