Calculations of S$_{2n}$ and $\delta<$r$^{2}>$ on long series of Kr, Rb, Sr and Xe, Cs, Ba isotopes

The density dependent Hartree-Fock method has been used to study the variation of the two neutron separation energies (S/sub 2n/) and of the mean square charge radii ( delta (r/sup 2/)). Correlations between anomalous S/sub 2n/, delta (r/sup 2/) and deformations have been analyzed. (5 refs).
