| Abstract: | A particle distribution due to coronal transport is presented based on maincharacteristics of solar flare particle transport in the corona. The Green function of theinterplanetary propagation equation with the source of the distribution is solved andthe solutions of high energy particle propagation in an infinite medium are obtainedby using the Green funtion. The intensity-time profiles given by numericalcalculations of the theory are compared with the observations for the event 23September 1973 from IMP-8, Hellos--1 and Hellos--2. The results show a goodagreement between theory and observations. |
