                         energy changes of the Van Allenīs outer radiation belt electron 
                         flux, violating the third adiabatic invariant, through a resonant 
                         interaction. The main mechanism involved is the radial diffusion, 
                         it is an stochastic process that take account the wave and the 
                         particle drift frequencies. There are some proposed models to 
                         explain the ULF-particle interaction deriving the radial diffusion 
                         coefficients. All the models consider the polarization modes of 
                         the ULF waves on the efficiency of the interaction. The 
                         contribution of the fluctuation of the magnetic and electric field 
                         are computed taking account the power spectrum density (PSD) of 
                         the signal. This work aims to estimate the behavior of the 
                         integrated ULF wave PSD amplitude, in the frequency range of the
