  Chandra X-ray observations of the 1 E0657-56 galaxy cluster diffuse emission
reveal the existence of large scale cluster merger shock. We study the observed
radio and X-ray data of this cluster as a possible result of the diffusive
shock acceleration. This model can explain the observations within reasonable
ranges of physical parameters for the shock and the intracluster medium. The
expected nonthermal soft and hard X-ray fluxes are predicted.
