The first optical measurements of the neutron deficient isotopes, 87-89Zr, and also the two long-lived isomers, 87m,89m Zr, have been performed using the new technique of collinear laser spectroscopy of cooled, bunched ion beams. Nuclear mean-square charge radii, spins, magnetic moments and quadrupole moments spanning the N = 50 shell closure are reported. The 'kink' in the charge radii trends at the neutron shell closure is the most pronounced observed for any element in the region.
