Using the Hartree-Fock-Bogoliubov (HFB) mean-field theory in coordinate space, we investigate ground-state properties of the zirconium isotopes from the line of stability up to the two-neutron dripline ( 102-122Zr). In particular, we calculate two-neutron separation energies, quadrupole moments, and r.m.s. radii for protons and neutrons. We find large prolate ground-state deformations for the isotopes 102Zr through 112Zr, and the spherical shapes starting from 114Zr up to the dripline nucleus 122Zr.
