Description

The scattering mean free paths of solar flare protons in the rigidity ranges 195-396 MV (20-80 MeV) and from about 1.5 to 5 GV for the May 7, 1978, solar cosmic ray event were found to be 1.7 ± 0.1 AU and 3.9 ± 0.4 AU, respectively. These scattering mean free paths are compared with those deduced for other scatter-free solar cosmic ray events. The rigidity dependence of λ11 can be described by λ[AU] = 2.0 (P[GV])0.4 for 0.1 < P < 5 GV
