Angular correlation of excitation functions in dissipative heavy ion collision 27A1+27A1 has been measured. The incident beam energies ranged from 114 MeV to 127 MeV in steps of 200 keV. The angular analysis region was continuous from 50° to 90° in the center of mass system. An angular coherent width, at least 40°, 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 27A1+27A1 with the state that is far from equilibrium.

Abstract
Angular correlation of excitation functions in dissipative heavy ion collision 27A1+27A1 has been measured. The incident beam energies ranged from 114 MeV to 127 MeV in steps of 200 keV. The angular analysis region was continuous from 50° to 90° in the center of mass system. An angular coherent width, at least 40°, 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 27A1+27A1 with the state that is far from equilibrium.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
