Abstract

A theoretical study of even–even nuclei (2 ≤ Z ≤ 8) with extreme neutron excess stable with respect to one-neutron emission, including nuclei beyond the neutron drip line (NDL), is performed. The calculations are based on the Hartree–Fock (HF) method with Skyrme forces (SkI2) and allowance for axial deformation and the Bardeen–Cooper–Schrieffer (BCS) pairing approximation. It is shown that beyond the NDL, 18He and 40C isotopes form peninsulas of nuclei stable with respect to one-neutron emissions. The restoration of stability beyond the NDL for 18He and 40C can be explained by the complete filling of neutron subshells with high angular momentum and the introduction of corresponding neutron levels in the region of discrete bound states.
