Fluctuation in the Dissipative Heavy Ion Collisions of FNb

doi:10.7523/j.issn.2095-6134.2003.3.007

Abstract

Abstract:

Two independent measurements of excitation functions in dissipative collisions of 19 F +93Nb have been carried out at incident energies from 100MeV to 108MeV in steps of 250 keV.The experimental conditions were kept to be identical in both measurements.The data indicate non-reproducibility of the non-self-averaging oscillating cross sections.The quasi-periodic structure in the energy autocorrelation functions is described by means of the concept of parity and spin decoherence in the intermediate dinuclear system.The non-reproducibility of the cross sections is interpreted by the extreme sensitivity of initial condition in the quantum chaotic motion.

Key words: fluctuation, non-self-averaging, non-reproducibility, decoherence, quantum chaos
