abstract = "The ULF frequency range are know to play a significant role on the
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
Pc3 and Pc5 geomagnetic pulsation on the magnetic field data
recorded ground based stations from the Churchill line disposition
of the Canadian Array for Realtime Investigations of Magnetic
Activity (CARISMA) magnetometer network, for all the cases that
have an increase on the 2.10 MeV electrons recorded by the
Relativistic Electron Proton Telescope (REPT) instrument, on board
of the Van Allen Probes, related to Coronal Mass Ejection (CME)
and High Speed Streams (HSS) events, during the October 2012 to
December 2016 period. This arrangement allows the verification of
the PSD according to the radial distance in the magnetosphere,
covering all the external radiation belt region.",
