Masung, L S; Earl, J A

A propagation model which combines a Gaussian profile for particle release from the Sun with interplanetary particle densities predicted by focused diffusion was proposed to explain the propagation history of flare-associated energetic particles. This model, which depends on only two parameters, successfully describes the time-intensity profiles of 30 proton and electron events originating from the western hemisphere of the Sun. Generally, particles are released from the Sun over a finite interval. In almost all events, particle release begins at the time of flare acceleration.
