Title: Investigation of cluster structure of {sup 9}Be from high precision elastic scattering data

Abstract

The cluster structure of {sup 9}Be has been investigated through high precision elastic scattering cross-section measurements of a {sup 9}Be + {sup 208}Pb system at below barrier energies, E= 24-34 MeV.The observed deviation from the Rutherford scattering can only be explained by an n + {sup 8}Be cluster description of {sup 9}Be, whereas the {alpha} + {sup 5}He cluster picture fails to explain the measured data, indicating the dominance of the n + {sup 8}Be cluster structure of {sup 9}Be. In addition to sequential and direct breakup, the coupling effect of one neutron stripping on elastic scattering is significant even at 10 MeV below the barrier. The sensitivity of the high precision elastic scattering data to the cluster structure of {sup 9}Be has been demonstrated.
