O(p,)F Reaction and the C and O Isotopic Ratios in Red Giant Branch Stars
D. Robb, P. McGlynn, M. Aliotta +55
The O/O isotopic ratio is a widely used tracer of nucleosynthesis and mixing processes in red giant stars. Its value depends on the rates of the proton-capture reacti…
First Proton-Induced Cross Sections on a Stored Rare Ion Beam: Measurement of 118Te(p,γ) for Explosive Nucleosynthesis
F. Dellmann, J. Glorius, Yu. A. Litvinov +75
We present the first nuclear cross-section measurements of (p,γ) and (p,n) reactions on 118Te at energies relevant for the γ-process nucleosynthesis. Absolute cross-section values…
Status and future directions for direct cross-section measurements of the 13C(a,n)16O reaction for astrophysics

Neutron emission probabilities and half-lives of 37 beta-delayed neutron emitters from 75Ni to 92Br were measured at the RIKEN Nishina Center in Japan, including 11 one-neutron and…
Investigation of Direct Nuclear Reactions in a Storage Ring Using In-Ring Detection
J. C. Zamora, T. Aumann, S. Bagchi +62
\textbf{Background:} Experiments involving nuclear reactions in a storage ring offer exceptional possibilities for precise measurements in inverse kinematics. These experiments pro…
A Comparative Analysis of R-Matrix Fitting: CN as Test Case
J. Skowronski, D. Piatti, D. Rapagnani +49
In nuclear astrophysics, the accurate determination of nuclear reaction cross sections at astrophysical energies is critical for understanding stellar evolution and nucleosynthesis…
