Map equations are derived, with which nonlinear electron motion in a coherent whistler wave packet is investigated. All solutions of these equations belong to a certain strange attractor and describe chaotic motion with the stable means. The class of solutions determined the intermittent dynamics as the control parameter of the wave-particle system increases above the appropriate critical value is found. An application of the results to the problem of the stability of Earth’s radiation belts is considered. It is shown that the efficient acceleration processes take place for relativistic electrons of a few MeV.

The distinctive feature of this regime is that the power lost by...
