    "abstract": "The study of the hyperfine (hfs) anomaly in neutron rich nuclei can give a\nvery specific and unique way to study the neutron distribution and the\nclustering structure. We study the sensitivity of the hfs anomaly to the\nclustering effects in the 9Be isotope using two different nuclear wave\nfunctions obtained in the three-cluster (alpha+alpha+n) model. The results are\ncompared to those obtained for 9,11Be in a two-body core + neutron model to\nexamine whether the hfs anomaly is sensitive to a halo structure in 11Be.",
