Abstract

The absorption of gamma radiation by photon-photon interactions in the core region of 3C273 has been reconsidered because 3C273 may be gravitationally lensed by a galaxy along the line of sight to the quasar. It is shown that the gamma radiation detected by COS-B can escape from the same compact core as the quasar's x-ray flux if the intensification of the gravitational lens is about 100.
