Résumé : | Photoneutron cross sections were measured for Zr96 near neutron threshold with quasimonochromatic laser-Compton-scattering γ-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 γ-ray strengths for zirconium isotopes that is described by the HFB + QRPA model of E1 strength supplemented with an extra γ strength attributed to a giant M1 resonance. Results of the systematic analysis including radiative neutron capture cross sections for radioactive Zr95 and Zr93 nuclei are presented. © 2010 The American Physical Society. |
