We determine the eigenfunctions and eigenvalues of the pitch-angle diffusion operator predicted by quasilinear diffusion theory and approximate plasma wave parameters for energetic electrons in the outer zone. We consider scattering alone and in concert from three wave populations: hiss, chorus, and EMIC. By projecting ptich-angle distributions observed by CRRES into the eigenfunctions, we can determine whether the pitch-angle distributions are consistent with the assumed diffusion process. Eigenmodes with shorter decay times (i.e., larger negative eigenvalues) ought to represent a comparatively smaller portion of the total flux in the pitch angle distribution. We use this technique to compare quiet-time and storm-time pitch-angle distributions, and to infer the relative contribution of different waves to the angular diffusion during those times.
