摘要：

We analyze the images of the Sagittarius Arm tangent obtained with the IBIS telescope of the INTEGRAL observatory in the energy range 18-120 keV during its observations in the spring of 2003. We detected 28 sources at a statistically significant level with fluxes above 1.4 mCrab in the energy range 18-60 keV. Of these sources, 16 were previously identified as binaries of various classes in our Galaxy, 3 were identified as extragalactic objects, 2 were identified as pulsars in supernova remnants, and 7 sources were of an unknown nature. These observations revealed three new sources. A statistically significant flux in the energy range 60-120 keV was recorded from 13 sources. (C) 2004 MAIK "Nauka/Interperiodica".
