Figure 14.

Left: Event‐driven pitch angle diffusion coefficients shown at L = 2.5, 3.5, 4.5, and 5.5 for energies between 50 keV and 6 MeV versus pitch angle (α) and computed from all wave and plasma properties (cf. Figures 12 and 13) for the period of October 3–9 (first column) and October 16–25 (second column). Right: Electron omnidirectional phase‐space density (PSD) simulated with the event‐driven pitch angle diffusion coefficients from October 3–9 (third column) and October 16–25 (fourth column) versus L and energy. The PSD decay shows the gradual decay of electrons in the slot region and in the outer belt that explains the gradual enlargement of the slot we see in the observations in Figure 6 for EPT and 7–9 for RBSP. Relativistic and ultra‐relativistic electrons (>1 MeV) are not scattered above L ∼ 3.5.
