| Abstract: |
We have studied the effect of internal structure of shock fronts on their efficiency of particle acceleration. We present a simple model of the width of a parallel shock front depending on the spectral index of the ambient magnetic turbulence. Using Monte-Carlo simulations, we determine the spectral index of energy distribution of shock accelerated particles in this model as well as in a case, where the shock width is independent of the ambient turbulence. In both cases, the acceleration capability of a wide shock structure is shown to be much smaller than for a step-like shock front. |
