Measurement of the Ce 140 (n,γ) Cross Section at n_TOF and Its Astrophysical Implications for the Chemical Evolution of the Universe
(2024-03-21)
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, ...
Neutron Capture on the s-Process Branching Point ^{171}Tm via Time-of-Flight and Activation
(2020-10-02)
The neutron capture cross sections of several unstable nuclides acting as branching points in the s process are crucial for stellar nucleosynthesis studies. The unstable ^{171}Tm (t_{1/2}=1.92 yr) is part of the branching ...
