B. ; Seaquist, E. R. Abstract The detection of H83-alpha and H99-alpha radio recombination lines in the Markarian-Seyfert galaxy Mrk 668 (=OQ 208) is reported. The emission mechanism for these lines is stimulated emission in the nuclear ionized gas by the compact nonthermal source in the nucleus. A simple model for this region which accounts for the radio lines is presented.
