Angular correlation of excitation functions in dissipative heavy ion collision 27Al+27Al has been measured. The incident beam energies ranged from 114MeV to 127MeV in steps of 200keV. The angular analysis region was continuous from 50°to 90°in the center of mass system. An angular coherent width, at least 4n° was obtained. This long-range angular correlation could not be interpreted in the framework of the standard statistical reaction theory with state of equilibrium or near equilibrium, maybe it reveals the formation of a new kind of dissipative structure in the reaction of 27Al+27AI with the state that is far from equilibrium.
