Analysis of energy autocorrelation functions in dissipative heavy ion collision of ²⁷Al+²⁷Al

Analysis of energy autocorrelation functions in dissipative heavy ion collision of 27 Al+ 27 Al 1 first-author 1 1 1 1 1 Institute of Modern Physics, the Chinese Academy of Sciences, 730000 Lanzhou Institute of Modern Physics, the Chinese Academy of Sciences, 730000 Lanzhou The excitation functions were measured in the reaction of 27 Al+ 27 Al at incident energies from 114MeV to 127MeV in steps of 200 keV. The detection angles were continuously covered from 10° to 57° in the laboratory system. The energy autocorrelation functions of the dissipative fragments were analyzed by using different approaches. The nonself-averaging oscillations in the excitation functions were considered due to the angular momentum coherence and damping of the coherent nuclear rotation. The damping results from a quantum chaotic motion. Excitation function mensurement Dissipative heavy ion collision Angular momentum coherence Quantum chaos References Rosa De A et al .
