Measurement of the Ce 140 (n,y) cross section at n_TOF and its astrophysical implications for the chemical evolution of the universe
(American Institute of Physics (AIP), 2024-03-21)
Article
Open Access140 Ce (n, y) 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, ... -
