Abstract: We investigate the effect of Raman scattering of photons from the O VI 1032 Å line on neutral atoms of hydrogen in the symbiotic binary AG Dra. We found that the profile of the Raman scattered O VI 6825 Å line can be fitted by two Gaussians. We have investigated the behavior of their parameters (position, flux at maximum, FWHM, and the corresponding total flux of the line) as a function of orbital phase and the level of activity. Differences in some parameters as measured during quiescent and active phases suggest a significant variation of the ionization structure of the binary as a function of the activity level.
