Abstract Magnetosonic waves have been demonstrated as effective for bounce resonant scattering. Electron scattering rates due to bounce resonance interaction with magnetosonic waves are derived in a general form, where the effects of the finite Larmor radius, of violation in the first adiabatic invariant, and of latitudinal wave power distribution are considered. Such bounce resonance diffusion coefficients are important, but missing, from radiation belt modeling. Additionally, we provide a parametric study on the electron energy and equatorial pitch angle, magnetosonic wave, and background parameters to identify the factors that determine effective bounce resonant scattering.
