AB: Both proposed acceleration mechanisms, radial diffusion and in-situ acceleration, can lead to electron flux enhancements in the outer radiation belt. In this presentation, we show evidence of flux increases during a narrow-band magnetospheric pulsation event, during which the energetic electron fluxes enhance more rapidly for those with drift frequencies close to the narrow-band pulsations. A simulation was performed to quantify and further investigate the drift resonant interaction: in the simulation an analytic model of magnetospheric fluctuations was parameterized to have characteristics similar to the observations on that day and 500.000 electrons were traced in the modeled fields. We found that the simulation results confirm a drift resonant interaction.
