Scientific paper

We present a model for the parallel transport of energetic particles which addresses the effects of propagation and thermal damping of waves, and time dependent decorrelation of magnetic fluctuations.The model is able to explain the observations of particle mean free paths ranging from keV electrons to GeV protons. In particular, it is found that the dynamical effects, leading to a strongly non-resonant pitch angle scattering through 90o at low rigidities, can be described by a single parameter which is estimated from the observed density, temperature and magnetic field strength in the solar wind. The predictive power of the model is then basically limited by the current lack of knowledge of the exact decomposition of the fluctuations. Possibilties to, conversely, use the energetic particles to probe properties of the fluctuations are discussed. Supported by NASA grant NAG5-11603.
