Interaction cross sections for nuclei with Z=2–12 on a 12C target are calculated in the Glauber model with matter densities obtained from Skyrme Hartree-Fock and relativistic Dirac potentials. The shell-model orbital occupations and separation energies are taken from configuration-mixing calculations and experimental spectroscopic data. Halo effects are present in the most neutron-rich C and N isotopes. The rms matter radii and interaction cross section exhibit a kink at N=14 which can be associated with a change in the mean-field potential when the 1s1/2 orbit is being filled.
