Abstract
The differential cross sections of the inelastic scattering leading to the excitation of short-lived states in the stable C and Be nuclei as well as the radioactive Be nucleus have been analyzed. Signatures of neutron halos in the excited states located close to the neutron emission thresholds have been investigated by applying a recently developed modified diffraction model. The abnormally large rms radius was identified for the 3.089-MeV state of C. Significantly enlarged diffraction radii were found for the 1.68-MeV and the 3.05-MeV states of Be. The analysis of the diffraction radii of the weakly bound radioactive Be nuclei have shown that the 1.78-MeV and 3.41-MeV states in Be have the same diffraction radii as the ground state, which is known as the best example of a state with one-neutron halo.
