Whistler mode wave-particle interaction in the earth's magnetosphere was investigated by a sounding rocket experiment performed at Siple Station, Antarctica, on January 4, 1978. The experiment observed intense bursts of X ray bremsstrahlung produced by precipitating electrons. The X ray data were compared to the VLF wave data recorded on the ground at Siple and its magnetic conjugate point, Roberval, Quebec. A time series analysis of the observations concluded that these Z ray bursts were significantly correlated with the Roberval VLF intensity in the 2-3 kHz frequency range. The average time delay of maximum correlation between the X ray flux and the VLF intensity was found to be small (less than .1 s). The experimental results were compared with theoretical predictions of the time delay between the arrival of the VLF emissions at Roberval and the arrival of the precipitating electrons at Siple. The model incorporated into the time delay calculations the variation of the emission frequency. Disagreement between the predicted and observed time delays suggested a separation of the wave generation and electron scattering regions.
