摘要：

The reaction Be-9 (Mg-28, Ne-26 + gamma)X has been studied at 82 MeV/nucleon together with two similar cases, Mg-30 and Si-34. Strong evidence that the reactions are direct is offered by the parallel-momentum distributions of the reaction residues and by the inclusive cross sections. The pattern of the partial cross sections for Mg-28 suggests the presence of correlations. A preliminary theoretical discussion based on eikonal reaction theory and the many-body shell model is presented. The reaction holds great promise for the study of neutron-rich nuclei.
