Resonant elastic scattering of α particles on 9Be and cluster states in 13C

We discuss the preliminary results obtained by studying the α+9Be elastic scattering at bombarding energies from 3.5 to 10 MeV. Experimental spectra show the presence of elastic and inelastic scattering phenomena. Elastic scattering excitation functions have been obtained at various angles; their shape is in good agreement with data at backward angles reported in the literature.
