Abstract
Nuclei at the neutron-drip line are studied. In particular, we analyse the binding energies with the effects of Coulomb repulsion, nuclear attraction due to proximity and rotational energy due to angular momentum. This includes the study of the `neutron-halo structure' of some 18 light neutron-rich nuclei. In terms of the neutron-cluster + core picture, the halo structures of these nuclei are identified which agree with the hypothesis of one/two neutron separation energies and are supported by available experimental information. All the studied nuclei possess 1n- or 2n-halo structure. It is further shown that these nuclei prefer stable cores with not only the neutron number N = 2Z but also with 2Z±2.
