Observation of source 4U18-I4 within the range 0.2-10 keV onboard Salyut-4 station
Abstract
Results of observation of a slow X-ray pulsar 4U1813-14 (GX17+2) on July 22, 1975 with "Philin" equipment in the mode of inertial orientation are presented. Observation duration was about 30 minutes. At that period of time radiation from the source was characterized by a slow counting rate in the 2 - 6 keV range (approximately 460 UHURU units), and by hard radiation spectrum. Approximation of the spectrum by the power law is studied. Interpretation of the results is presented and discussion of the physical structure of this pulsar.
