High-Resolution Cross Section Measurements for Neutron Interactions on *8*9Y with Incident Neutron Energies up to 95 keV / G.Tagliente, V.Furman, Y.Kopatch, [a.o.] // The European Physical Journal A [Electronic resource]. – 2024. – Vol. 60, No. 1. – P. 21. – URL: https://doi.org/10.1140/epja/s10050-024-01243-4. – Bibliogr.: 66.

The cross section of the 89Y(n, γ ) reaction has important implications in nuclear astrophysics and for advanced nuclear technology. Given its neutron magic number N = 50 and a consequent small neutron capture cross section, *8*9Y represents one of the key nuclides for the stellar s-process. It acts as a bottleneck in the neutron capture chain between the Fe seed and the heavier elements. Moreover, it is located at the overlapping region, where both the weak and main s-process components take place. *8*9Y, the only stable yttrium isotope, is also used in innovative nuclear reactors. Neutron capture and transmission measurements were performed at the time-of-flight facilities n_TOF at CERN and GELINA at JRC-Geel. Resonance parameters of individual resonances were extracted from a resonance analysis of the experimental transmission and capture yields, up to a neutron incident energy of 95 keV. Even though a comparison with results reported in the literature shows differences in resonance parameters, the present data are consistent with the Maxwellian averaged cross section suggested by the astrophysical database KADoNiS.
