Abstract

The X-ray spectrum of QSO 0241 + 622 in the range 2-50 keV measured with the Goddard Space Flight Center proportional counters on OSO 8 is presented. The quasar is similar to 3C 273 in the proportion of energy emitted in various bands, excluding the radio, if reported radiation above 50 keV from its direction is indeed associated with QSO 0241 + 622. Comparisons are made between the two quasars in a discussion of possible energy generation scenarios. Implications concerning quasar contributions to the diffuse background are discussed.
