(a) Wave amplitudes assumed in the diffusion coefficient calculations, as a function of $L$ for all $Kp$. (b–f) Bounce‐averaged pitch angle diffusion coefficients, $<D_{\alpha \alpha }>$, as a function of equatorial pitch angle and energy due to the indicated scattering mechanism (rows) at various $L$ (columns), for $Kp$ = 0.
