摘要：
The structure of Be-12 is investigated using a microscopic alpha+alpha +4n model based on the molecular-orbit (MO) model. It is shown that the remarkable alpha -clustering and the contribution of the spin-orbit interaction make the binding of the state with the (3/2(-))(2)(1/2(+))(2) configuration for the valence neutrons properly stronger in comparison with the closed p-shell (3/2(-))(2)(1/2(-))(2) configuration. The molecular-like structure of the C isotopes is also investigated using a microscopic alpha+alpha+alpha +n+n+(...) model.
