Abstract

We performed a statistical analysis of the intrinsic properties of long gamma-ray bursts(GRBs) observed by Swift. The intrinsic quantities are the rest-frame durationT90,rest, the rest-frame peak energyEp,rest, the isotropic equivalent energyEiso and the peak luminosityLiso of the prompt emission. We find that the distributionsof T90,rest,Ep,rest, Eisoand Liso all span a wide range and the central values of theseintrinsic quantities of long GRBs areT90,rests10s,Ep,rests520keV,Eisos1053 erg andLisos4 × 1052 erg/s. We also find bothEp,rest andLiso are independent with T90,but Eiso is correlated withT90.
