Abstract
EXAFS in the soft X-ray range from intramolecular, low Z backscattering has been investigated in the inner shell spectra of gaseous CO, CO2, CF4, c-C6H12, C6H6 and C6F6, recorded by inelastic electron scattering in the dipole regime. The 01s continua of CO and CO2 do not exhibit the oscillations recently reported by Yang et al (Phys. Lett A110 (1985) 301). The Cls spectrum of CF4 contains extended continuum features similar to those reported previously. The Cls continua of c-C6H12, C6H6 and C6F6 exhibit weak extended continuum features which appear to be EXAFS although the analysis procedures used so far are not able to reproducibly extract accurate bond lengths.
