  The acceleration of energetic particle transport in high amplitude
magnetosonic and Alfvenic turbulence is considered using the method of Monte
Carlo particle simulations, involving integration of particle equations of
motion. We derive the momentum diffusion coefficient in the presence of
anisotropic turbulent wave in the high-magnetized plasma, for a flat and
Kolmogorov-type turbulence spectrum. We confirm the quasilinear result
(Shlickeiser & Miller (1997) of enhanced values of the momentum diffusion
coefficient due to transit-time resonance interaction in the presence of
isotropic fast-mode waves as compared to the case of slab Alfvenic waves of the
same amplitude. The relation of the momentum diffusion coefficient to the
turbulence amplitude and anisotropy is investigated.
