Scientific paper

Spectropolarimetric observations of the symbiotic stars He2 - 38 and RX Pup in the range 6700-7600 A are reported. In He2 - 38, there is a polarization of 5.3 and 9.2 percent in the emission features at 6825 and 7082 A, respectively, while other emission lines as well as the continuum remain unpolarized. In RX Pup only a weak continuum polarization is detected. The polarization observed in He2 - 38 strongly supports the recent identification of these lines as due to Raman-scattered O VI 1032-A and 1038-A photons (Schmid, 1989).
