Photoneutron cross sections were measured for {sup 96}Zr near neutron threshold with quasimonochromatic laser-Compton-scattering {gamma}-ray beams. A systematic analysis of photoneutron and radiative neutron capture data for zirconium isotopes within the statistical model calculation leads to a unified picture of low-energy {gamma}-ray strengths for zirconium isotopes that is described by the HFB + QRPA model of E1 strength supplemented with an extra {gamma} strength attributed to a giant M1 resonance. Results of the systematic analysis including radiative neutron capture cross sections for radioactive {sup 95}Zr and {sup 93}Zr nuclei are presented.
