摘要The giant X-ray bump of GRB 121027A observed by Swift is different from the typical X-ray flares in gamma-ray bursts. The observed structural variability in the rise and decay phases of the bump has four components. Of these four components, only the data in the bump from about 5300 to about 6100 s is of good enough quality to be analysed using the stepwise filter correlation method. A 86(-9.4)(+5.9)s periodic oscillation is postulated, which is confirmed by the Lomb-Scargle method. A jet precession model is proposed to account for this variability.
