English Abstract

Shape evolution for Ne, Mg, Si, S, Ar, and Ca isotopes have even number of neutrons and that are claimed to be in or nearby the A ≈ 30 mass region of the nuclear chart are studied using covariant density functional theory (CDFT), based on finite range NN-interaction force represented by NL3∗ and DD-ME2 and zero finite range NN-interaction force represented by DD-PC1.

The ground state shape is found to be both oblate and prolate in 26 Mg and 26Si.

The spherical shape is obtained for the Ca isotopes, and for nuclei that have magic neutron number N = 8 and 20.

The rest of the isotopic chain has only one minimum and alternate between prolate and oblate shapes.

Physical properties are calculated at the location of ground-state deformation as the change with neutron number (N) and proton number (Z), such as the binding energy, two-neutron separation energies, proton, neutron and charge radii.

In general, a smooth change in these properties is found, except near N = 8 and 20 one can see a sharp change, which reflects the sudden change in the ground state deformation in the neighboring nuclei.

A very good agreement is found with the available experimental data, HF, and FRDM models.
