Propagation of Solar Energetic Particles in Three-dimensional Interplanetary Magnetic Fields: Radial Dependence of Peak Intensities

H. -Q. He, G. Zhou, W. Wan

A functional form I_{max}(R)=kR^{-α}, where R is the radial distance of spacecraft, was usually used to model the radial dependence of peak intensities I_{max}(R) of solar energeti…
