THE PROPERTIES OF CROSS-CORRELATION AND SPECTRA OF THE LOW-MASS X-RAY BINARY 4U 1608-52
With {\it RXTE} data, we analyzed the cross-correlation function between the soft and hard X-rays of the transient atoll source 4U 1608-52. We found anti-correlations in three outbursts occurred in 1998, 2002 and 2010, and significant time lags of several hundreds of seconds in the latter two outbursts. Our results …
