Bulk properties like binding energies, rms radii, and quadrupole deformations of Ca, Ti, Cr, Fe, Ni, and Zn nuclei are calculated in the deformed relativistic mean field model. Excellent results for the experimentally known binding energies and radii of nuclei are obtained. The calculation is extended to nuclei near the neutron-drip line. Dips in quadrupole deformation are seen for the known closed-shell configurations and enhanced deformations are obtained for specific neutron numbers.
