nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier
isotopes passes through the neutron magic nucleus Zr 90 and through Zr 91, 92, 93, 94, but
only part of the flow extends to Zr 96 because of the branching point at Zr 95. 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 Zr 94 (n, γ) cross section has been …
