FOURIER-ANALYSIS OF NONSELF-AVERAGING QUASI-PERIODIC OSCILLATIONS IN THE EXCITATION-FUNCTIONS OF DISSIPATIVE HEAVY-ION COLLISIONS - QUANTUMCHAOS IN DISSIPATIVE HEAVY-ION COLLISIONS

We employ stochastic modelling of statistical reactions with memory to study quasiperiodic oscillations in the excitation functions of dissi pative heavy-ion collisions. The Fourier analysis of excitation functi on oscillations is presented. It suggests that S-matrix spin and parit y decoherence, damping of the coherent nuclear rotation and quantum ch aos are sufficient conditions to explain the nonselfaveraging of quasi periodic oscillations in the excitation functions of dissipative heavy -ion collisions.
