Popis: Cross-sections for the production of 210Po nuclei in 6He + 206Pb collisions over the incident energy range 14-18 MeV were measured by means of the activation technique and a radiochemical analysis. The elastic scattering at 18.0 MeV was also measured providing a precise value for the 210Po production cross-section at this energy. The results are at variance with the earlier experimental data and rather in accord with the predictions of a density-dependent barrier penetration model for the fusion process. A proper treatment of beam energy distribution for the evaluation of the activation data is discussed. © Società Italiana di Fisica/Springer-Verlag 2011.
