| 摘要 | Using 64 ms count data of long gamma-ray bursts (T-90 > 2.6 s), we analyze the quantity named relative spectral lag (RSL), tau(31)/FWHM(1). We investigated in detail all the correlations between the RSL and other parameters for a sample of nine long bursts, using the general cross-correlation technique that includes the lag between two different energy bands. We conclude that, the distribution of RSLs is normal and has a mean value of 0.1; that the RSLs are weakly correlated with the FWHM, the asymmetry, peak flux (F-p), peak energy (E-p) and spectral indexes (alpha and beta), while they are uncorrelated with tau(31), the hardness-ratio (HR31) and the peak time (t(m)). Our important discovery is that redshift (z) and peak luminosity (L-p) are strongly correlated with the RSL, which can be measured easily and directly, making the RSL a good redshift and peak luminosity indicator. |
