Application of correlation function in the fluctuation of excitation function in dissipative nuclear reaction

The correlation function method is applied to analyze the fluctuation of th e excitation function in the dissipative nuclear reaction. By deriving the energy autocorrelation function, angle correlation function, elements corre lation function and isotopic element correlation the characters of the nucl ear reaction system in the dissipative reaction varying from the equilibriu m to the non-equilibrium system are analyzed, and the special role of these method in the study of the dissipative nuclear reactions shown. Experiment s of 4.5MeV/u Al-27 + Al-27 and 102. 5MeV F-19 + V-51 are analyzed by using these function derived in this articles, and the information in dissipativ e nuclear system, which can be drawn out from this method, is pointed out.
