Description
The neutron capture cross sections of the Zr isotopes play an important role in nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier isotopes passes through the neutron magic nucleus 90Zr and through 91,92,93,94Zr, but only part of the flow extends to 96Zr because of the branching point at 95Zr. Apart from their effect on the s-process flow, the comparably small isotopic (n,γ) cross sections make Zr also an interesting structural material for nuclear reactors. The 94Zr (n,γ) cross section has been measured with high resolution at the spallation neutron source nTOF at CERN and resonance parameters are reported up to 60 keV neutron energy.
