Abstract:
We investigate here the effect on the emitted spectrum of a black hole binary due to the presence of accelerated protons in the inner region of the accretion disk. Our study shows that e-e+ pairs and high energy -rays created in inelastic p - p collisions contribute mainly in the 1 - 10 MeV range and produce a broad feature in the spectrum in this energy range which can be verified by INTEGRAL and GLAST observations.
