摘要：
A Gaussian whistler pulse is shown to cause ponderomotive acceleration of electrons in a plasma when the peak whistler amplitude exceeds a threshold value and the whistler frequency is greater than half the cyclotron frequency, ω>ωc/2. The threshold amplitude decreases with the ratio of plasma frequency to electron cyclotron frequency, ωp/ωc. However, above the threshold amplitude, the acceleration energy decreases with ωp/ωc. The electrons gain velocities about twice the group velocity of the whistler.
