摘要: We present the results of our hard X-ray and gamma-ray study LMXB Sco X-1 utilizing INTEGRAL data as well contemporaneous RXTE PCA data. have investigated spectral properties including nature high-energy, nonthermal component its possible correlations with location source on soft color-color diagram. find that follows two distinct tracks when 20-40 keV count rate is greater than 130 counts/second. One state a which exhibits significant powerlaw tail to lower energy thermal spectrum. The other shows much less high-energy component. found suggestive evidence for correlation these states position low-energy searched similar behavior in 2 Z sources: GX 17+2 5-1 negative results.
