Bounce and MLT averaged diffusion rates due to gyroresonance scattering by plasmaspheric hiss, lightning generated whistlers, and whistlers due to VLF transmitters inside the plasmasphere; and chorus waves outside the plasmasphere; are computed in high resolution in pitchangle. The computed rates show that another scattering mechanism is required to provide pitch-angle scatting for nearly equatorially mirroring particles at low energies outside the plasmasphere and at a wide range of energies in the slot region. We show that magnetosonic waves and ElectroMagnetic Ion Cyclotron (EMIC) waves can be in bounce resonance with electrons for a wide range of energies and pitch-angles, and may be responsible for the scattering of electrons with equatorial pitch-angels close to 90 degrees. Bounce resonance may also result in an in-situ acceleration of equatorially mirroring particles. Citation: Shprits, Y. Y.
