note = {The motions of relativistic particles in a magnetosonic shock wave propagating obliquely to an external magnetic field are studied. In the zeroth-order theory, particles continue to move nearly parallel to the external magnetic field in the shock transition region, when the shock speed is close to c cos θ, where c is the speed of light and θ is the propagation angle. Perturbations to this zeroth-order motion are also analyzed for positrons and ions. The perturbation frequency of positrons is ω ∼ Ω_p0γ^{−1} and that of ions is ω ∼ Ω_i0γ^{−1/2}, where Ω_p0 and Ω_i0 are the non-relativistic gyrofrequencies of positrons and of ions, respectively, and γ is the Lorentz factor. These theoretical predictions are confirmed with numerical simulations.},
