Vigorous research over the past several years has narrowed the search for acceleration mechanisms for outer zone MeV electrons to two main candidates: enhanced diffusive radial transport by ULF waves and local stochastic acceleration by VLF waves. Because the drivers of both potential acceleration mechanisms are enhanced during magnetic storms, it is difficult, from correlation analyses alone, to determine which of the two mechanisms is most relevant at each L shell. Further complicating matters is the enormous challenge of comprehensively measuring the relevant wave spectra in space, frequency, and wave number (k-vector). Nonetheless, a combination of empirical and theoretical arguments allows us to construct a working hypothesis of dual acceleration, with VLF waves being the likely mechanism at lower L shells and ULF waves being the likely mechanism at higher L shells. The presentation concludes with suggestions for future analyses that might better delineate the two mechanisms.
