Abstract

Two independent measurements of cross sections for the 19F+93Nb strongly dissipative heavy-ion collisions have been performed at incident energies from 102 to 108 MeV in steps of 250 keV. In the two measurements we used different, independently prepared, 93Nb target foils with the thickness ~70 ug/cm2. All other experimental conditions were identical in both experiments. The data indicate non-reproducibility of the non-self-averaging oscillating yields in the two measurements. This supports recent theoretical predictions of spontaneous coherence, slow phase randomization and extreme sensitivity in highly excited complex quantum systems.
