A Simulation on the Propagation of Supernova Cosmic Particles in a Fractal Medium.

In this paper, we present a mont carlo simulation by using the inhomogeneous diffusionequation suggested by lagutin et al. in a fractal interstellar medium for a supernova, as being the mainsource of galactic cosmic rays in an energy range up to 1016ev. when the numerical results of thissimulation are compared with the predicted energy density of cosmic rays from the supernova model oferlikyn and wolfendale (ew), they show a strong consistency with the observed experimental parametersof cosmic rays, i.e. galactic radial gradient, percentage of total supernova energy transfer to cosmicparticles etc., which is also conrmation of a supernova being of cosmic ray origin
