Scientific paper

We present BeppoSAX observations of the γ-ray emitting quasars 0836+710, 1510-089 and 2230+114. All the objects have been detected in the PDS up to 100 keV and have extremely flat power-law spectra above 2 keV (αx=0.3-0.5). 0.836+710 shows absorption higher than the galactic value and marginal evidence for the presence of the redshifted 6.4 keV Iron line. 1510-089 shows a spectral break around 1 keV, with the low energy spectrum steeper (αl=1.6) than the high energy power-law (αh=0.3). The data are discussed in the light of current Inverse Compton models for the high energy emission. .
