Wave-particle interactions in a magnetic neutral sheet
Abstract
The effect of an electrostatic wave on the motion of particles in a magnetic neutral sheet is studied. The first-order perturbation of the distribution function is conveniently obtained by a method in which the changes in the zero-order constants of the motion are calculated. Simple analytic approximation is possible in certain regions of velocity space, but it is shown that in general numerical calculation is required. Some sample numerical results are presented and the conditions for waveparticle resonance discussed.
