  We have reanalysed the ASCA X-ray spectrum of the bright symbiotic star CH
Cyg, which exhibits apparently distinct hard and soft X-ray components. Our
analysis demonstrates that the soft X-ray emission can be interpreted as
scattering of the hard X-ray component in a photo-ionised medium surrounding
the white dwarf. This is in contrast to previous analyses in which the soft
X-ray emission was fitted separately and assumed to arise independently of the
hard X-ray component.
  We note the striking similarity between the X-ray spectra of CH Cyg and
Seyfert 2 galaxies, which are also believed to exhibit scattering in a
photo-ionised medium.
