Hartree-Fock Calculation of Nuclear Binding Energy of Sodium Isotopes
Recents measurements  of the nuclear binding energy (B) of exotic sodium isotopes have shown that the two neutron separation energy B2n, defined as B2 (A,Z)= B(A,Z)−B(A−2,Z) displays a sudden discontinuity for the mass number A=31 (see fig.1) which is very similar to those observed in the rare earth region. In the latter case this phenomenon has been explained in terms of a shape transition of the intrinsic ground state.
