Abstract
Vela X-1 has been observed by the Italian/Dutch X-ray satellite BeppoSAX during its Science Verification Phase. During the ~ 50 ksec observation (orbital phases 0.27-0.34) two different intensity state are present, situation very common in this source. We report results from the pulse phase averaged and pulse phase resolved spectroscopy from the high-energy instrument PDS aboard BeppoSAX.
