Abstract
The kinetic energy (KE) distribution and asymmetry parameter β have been studied for photofragmentation of SF 6 near the sulfur 2p ionization edges at 170–208 eV. The relative ion yield at KE > 5 eV is higher in the post-edge than in the pre-edge region, whereas β is lower by ∼0.06 in the post-edge region. These results are ascribed to LVV Auger decay occurring above the edges. At KE > 2 eV the distribution curve for core excitation to the (2t 1u) −1(6a 1g) 1 state resembles that for valence-electron ionization, suggesting participation of shake-up satellite states in production of fast F + ions.
