title = "Measurement of the Ce 140 (n,γ) Cross Section at n\_TOF and Its Astrophysical Implications for the Chemical Evolution of the Universe",
abstract = "Ce140(n,γ) is a key reaction for slow neutron-capture (s-process) nucleosynthesis due to being a bottleneck in the reaction flow. For this reason, it was measured with high accuracy (uncertainty ≈5\%) at the n\_TOF facility, with an unprecedented combination of a high purity sample and low neutron-sensitivity detectors. The measured Maxwellian averaged cross section is up to 40\% higher than previously accepted values. Stellar model calculations indicate a reduction around 20\% of the s-process contribution to the Galactic cerium abundance and smaller sizeable differences for most of the heavier elements. No variations are found in the nucleosynthesis from massive stars.",
