Abstract：
Two independent measurements of excitation functions in the dissipative collisions of ¹⁹F+⁹³Nb have been performed at incident energies from 100 to 108 MeV in steps of 250 keV. The two measurements differed by the thickness of the target foils, 70μg/cm² and 71μg/cm², respectively. All the other experimental conditions, the accelerator, the incident energies and steps, the scattering chamber, the detection system, the electronics, the acquisition system and all the parameters selected in the two measurements, were kept to be identical in both experiments. The data indicate non-reproducibility of the non-self averaging oscillating yields in the two independent measurements. The indication of the non-reproducibility of the cross sections is discussed.
