Cosmic Ray Perpendicular Diffusion Coefficient and Drift Velocity Calculated from Pioneer/Voyager Observations

Abstract

The radial and latitudinal gradients measured by the Pioneer 10 and Voyager 1 and 2 spacecraft, reported by Cummings and Stone (1990), provide a unique opportunity to calculate the cosmic ray perpendicular diffusion coefficient and drift velocity.
