Abstract : The report points out that the anomalously low alpha/p flux ratio measured at L approximately = 3 can be understood qualitatively in terms of radial diffusion driven primarily by fluctuating electrostatic convection fields; when proper account is taken of charge exchange and pitch angle loss processes. Furthermore, it is shown that electrostatic radial diffusion seems to explain proton flux profiles better than magnetic diffusion, for energies less than a few MeV. (Author)
