Abstract
We report new experimental data concerning the elastic scattering of α-particles on 9Be nuclei in the bombarding energy region from 3.48MeV up to 9.94MeV, where a considerable lack of data exists in the literature. Data have been obtained at 110°, 135°, 150°, 160° backward polar angles suitable for IBA measurements. Excitation functions show various anomalies that can be linked to the presence of various excited states in the 13C compound nucleus. The present data have been compared with data reported in the literature, and an overall consistency is observed. The quality of the obtained excitation function at 160° has been benchmarked by performing EBS of α-particles on a thick and pure 9Be target at two bombarding energies.
