“…Peak 6 (maximum at 59.18 eV) in the TPE spectrum also has no counterpart in the 110 photoelectron spectrum. It may be associated with the (3t 1u ) → (4e g ) shape resonance predicted by one-electron MSM Xα calculations and tentatively assigned to a peak found near 58-60 eV photon energy in the relative partial cross section for the sum of the inner-valence levels [30]. Again, we attribute these peaks (5 and 6) in the TPE spectrum to indirect processes.…”

The threshold photoelectron (TPE) spectrum of SF 6 has been recorded over the photon energy range 25-140 eV using synchrotron radiation and a penetrating-field electron spectrometer. In addition, the photo-double ionization spectrum of SF 6 has been obtained over the energy range 30.7-49.3 eV using the threshold photoelectrons coincidence technique. The TPE spectrum in the inner-valence ionization region is found to be significantly different to the conventional photoelectron spectrum in the same binding energy region. Indirect autoionization of neutral Rydberg and shape-resonance states of SF 6 dominate the formation of the TPE spectrum. Innervalence SF + 6 ion states appear to play a major role in the formation of the SF 2+ 6 ion states. The onset of double ionization in SF 6 was found to occur at 31.98 ± 0.02 eV.

“…Decaying states ͑resonances͒ and their nuclear dynamics play a decisive role also in many other processes. In molecular photoionization cross section measurements the effect of short-lived resonances has been widely observed [9][10][11] for valence electrons and also for core electrons. It is well known that molecular resonances also markedly influence the electron-molecule scattering cross sections.…”

The correspondence between the time-dependent and time-independent molecular dynamic formalisms is shown for autoionizing processes. We demonstrate that the definition of the inner product in non-Hermitian quantum mechanics plays a key role in the proof. When the final state of the process is dissociative, it is technically favorable to introduce a complex absorbing potential into the calculations. The conditions which this potential should fulfill are briefly discussed. An illustrative numerical example is presented involving three potential energy surfaces.
