摘要:

Several gamma‐ray bursts in the BATSE data have sufficiently long durations and complex temporal structures with pulses that appear to be spaced quasi‐periodically. In order to test and quantify these periods we have applied fast Fourier transformations (FFT) to all these events. We have also performed cross spectral analyses of the FFT of the two extreme (high‐low) energy bands in each case to determine the lead/lag of the pulses in different energies.
