چکیده انگلیسی
We have studied the nature of the S 2p â 4eg shape resonance in the SF6 molecule by performing two different experiments. Soft X-ray emission spectra measured at the 4eg shape resonance reveal features that do not originate from the S 2pâ1 states. One of the features can be assigned to the 6a1g â S 2p transition. The 6a1g orbital, which is empty in the molecular ground state, can be populated either in core-valence double excitations or in S 2p shake-up transitions. Both these channels are considered. We have also studied the fragmentation of SF6 molecule after the decay of the S 2p core-hole states by observing neutral fragments in high-Rydberg states, where an electron occupies an orbital with n â¥Â 20 (n is the principal quantum number). Such neutral fragments become, in relative terms, more abundant at the S 2p â 4eg shape resonance with respect to the S 2p â 2t2g shape resonance, which is a pure one-electron phenomenon.
