Abstract

The energy density formalism has been applied to calculations of bulk properties of light stable and unstable nuclei with 1 ≦ Z ≦ 8 and to Na, K and Rb isotopes. The results emphasize many interesting features arising from the self-consistency. The most striking effect is the appearance of N = 16, 34 and 58 as neutron magic numbers for unstable nuclei, together with a weakening of the shell closure at N = 20 and 28. In spite of its intrinsic limitations, the general accuracy is sufficient for the model to be of practical use. For instance, the predictions concerning the drip lines are in good agreement with the experimental situation. Finally, the influence of the neutron excess on the interaction barrier is briefly discussed.
