    摘要: A peculiar wave event was recorded in the whistler frequency range at around a few hundred Hz, at a
    dipolarization site near the magnetic equator, about 10 Earth radii tailside. The THEMIS mission observed
    this wave event during an intense decrease in the auroral electrojet index (AL). The wave event is unique,
    with a shift in the wave normal angle from nearly 160o to 20o, right after the dipolarization angle reaches
    its maximum. The effect of pitch angle scattering on electrons through cyclotron and Landau resonances
    via this wave event is investigated by performing test particle simulations incorporating the observed wave
    amplitudes and wave normal angles. The results showed that the primary scattering could occur at nearly
    0 and 180 degrees for electrons around 10 keV, similar to the observed changes in electron pitch angle
    distributions of a similar energy. We will present the observations and computations and show that a wave
    event with shifted wave normal angles can cause changes in pitch angle distributions in different
    directions with respect to the ambient magnetic field.
