1] We present the equatorial and bounce-averaged pitch angle diffusion coefficients for the scattering relativistic electrons by He + -mode electromagnetic ion cyclotron waves. Both the model (prescribed) and self-consistent distributions over the wave normal angle are considered. The main results of our calculation can be summarized as follows: First, in comparison with field-aligned waves, intermediate and highly oblique waves decrease the bounce-averaged scattering rate near the edge of the loss cone by up to orders of magnitude if the electron energy does not exceed a threshold ($2–5 MeV) depending on specified plasma and/or wave parameters. Second, for greater electron energies, oblique waves operating the jnj > 1 resonances are more effective and provide the same bounce-averaged diffusion rate near the edge of the loss cone as field-aligned waves do.
