Resonant ion acceleration (the υ_p×B acceleration) in laminar magnetosonic shock waves is studied by theory and simulation. Theoretical analysis based on a two-fluid model shows that, in laminar shocks, the electric field strength in the direction of the wave normal is about (m_i/m_e)^<1/2> times larger for quasi-perpendicular shocks than that for the quasi-parallel shocks, which is a reflection of the fact that the width of quasi-perpendicular shocks is much smaller than that of the quasi-parallel shocks. Trapped ions can be accelerated up to the speed about υ_A(m_i/m_e)^<1/2>(M_A-1)^<3/2> in quasi-perpendicular shocks. Time evolution of self-consistent magnetosonic shock waves is studied by using a 2-1/2 dimensional fully relativistic, fully electromagnetic particle simulation with full ion and electron dynamics. Even a low-Mach-number shock wave can significantly accelerate trapped ions by the υ_p×B acceleration. The resonant ion acceleration occurs more strongly in quasi-perpendicular shocks, because the magnitude of this acceleration is proportional to the electric field strength.
