Abstract
Radial diffusion coefficients for low‐energy protons in the magnetosphere are estimated for processes involving Pc 1, 2, and 3 hydromagnetic waves. These diffusion coefficients are compared to rough estimates of diffusion due to magnetic impulses and bays, to arrive at an overall diffusion rate. An effective loss rate for ptich‐angle diffusion (caused by Pc 1) is developed, and combined with radial diffusion to yield a nonlinear differential equation. Some estimates of expected proton flux levels are made on the basis of this equation.
