Origin of MeV gamma-ray emissions from blazars

We have developed a model for MeV emission from blazars that involves the p roduction of MeV gamma-rays through Inverse Compton (IC) scattering of elec trons in the blob of a jet, with the UV photons of the accretion disk. The OSSE and the COMPTEL spectra of PKS 0528 + 134 have been fitted with the co mputed MeV gamma-ray fluxes of the above model. A good fit was obtained wit h electrons of Lorentz factor of 10(1.5) to 10(3) and a jet with viewing an gle of less than or equal to 15 degrees and an accretion disk temperature i n the range of 2.0 to 6.0 x 10(5) K.
