Abstract：
Two independent measurements of excitation functions for the ¹⁹F+ ⁹³Nb dissipative heavy ion collisions have been performed at incident energies from 100 to 108 MeV in steps of 250 keV. The two measurements differed by two target foils, 70 and 71μg/cm ², respectively. All the other experimental conditions were kept to be identical in hath experiments. The data indicate nonreptaludbility of the non-self-averaging oscillating yields in the two measurements. This supports recent theoretical predictions of extreme sensitivity and chaos in complex quantum collisions.
