Abstract : Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear technology. Therefore, the 92Zr(n,γ ) cross section has been remeasured at the CERN n TOF facility, providing a set of improved parameters for 44 resonances in the neutron energy range up to 40 keV.With this information the cross-section uncertainties in the keV region could be reduced to 5% as required for s-process nucleosynthesis studies and technological applications.
