Abstract

We have searched the rising portion of type I X-ray bursts observed from the Rapid Burster with the Rossi X-ray Timing Explorer for the presence of periodicities. The 95 per cent confidence upper limit on the average rms variation of near coherent pulsations with a width of ≲1 Hz (in 60-2048 Hz) during the first second of the bursts is <8.8 per cent. We find a possible detection (>98per cent significance) at 306.5 Hz.
