摘要：
We will discuss new experimental data concerning the elastic resonant scattering of alpha-particles on Be-9 nuclei at bombarding energies from 3.5 MeV up to 9.9 MeV. Several excitation functions have been obtained at different polar angles, mainly in the backward hemisphere in the centre of mass frame. Excitation functions show various anomalies that can be linked to the presence of various excited states in the C-13 compound nucleus. In the literature, some of these states have been proposed to belong to rotational bands built on deformed alpha-cluster excited state. Unfortunately, up to date the spin-parity assignment of many of these states is doubtful. The set of excitation functions we obtained from the present experiment can contribute to improve spectroscopy of high-ling excited states of C-13.
