Absorption structures of SF₆in the VUV region

Abstract

Absorption and ionisation efficiencies for SF6 have been measured in the VUV region. An analysis of the gross absorption structures is given by comparison of the experimental results in photoelectron spectroscopy with the absorption spectra of the sulphur L2,3. All the absorption structures in the VUV region observed are interpreted consistently with the two-well potential scheme. The vibrational progressions in the range 550-670 AA are also assigned to the Rydberg series caused by the transitions, 4t1u-nsa1g (n>or=3).
