  Deformed Hartree-Fock-Bogoliubov calculations for finite nuclei are carried
out. As residual interaction, a Brueckner G-matrix derived from a
meson-exchange potential is taken. Phenomenological medium modifications of the
meson masses are introduced. The binding energies, radii, and deformation
parameters of the Carbon, Oxygen, Neon, and Magnesium isotope chains are found
to be in good agreement with the experimental data.
