Scientific paper

Cyg X-1 is the brightest of the persistent black hole candidates and shows transitions from high to low states. The features of its spectrum can be explained with a model in which a Shakura-Sunyaev disc is present in an external region and an optically thin and geometrically thick corona is present in an internal region. The so called ADAF models could naturally explain the presence of the hot inner region. However They predict a transition radius greater than 100 Schwarzschild radii in the low (hard) state. On the contrary our broad band (0.1-100 keV) spectral analysis, performed on BeppoSAX data, reveals that the reflected component is relativistically smeared and the inferred transition radius is small as 10 Schwarzschild radii.
