Observations from a recent rocket experiment that measured electrons over the energy range of 1--300 keV shows that microburst temporal structures exist from about 20 keV to >120 keV. Simultaneous observations at five different pitch-angles (0¿--90¿) show the distribution is nearly isotropic during the bursts, while at low activity (quiet times and the valleys between microbursts) the distribution is anisotropic with higher fluxes at larger pitch-angles. The energy spectra were reasonably fit with a Maxwellian, with an e-folding energy E0≈6--9 keV for &agr;=0¿, which increases to ≈10 keV at 67¿. A modeling of electron spectra using the theory of pitch-angle diffusion can reproduce the observed spectra, suggesting pitch-angle scattering of electrons due to a wave-particle interaction is the primary mechanism responsible for microbursts. ¿ American Geophysical Union 1996
