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…
A prototype neutron-detector array for future deep-underground s-process studies
Thomas Chillery, David Rapagnani, Chemseddine Ananna +12
We report a novel neutron-detection approach employing an EJ-309 liquid scintillator surrounded by six 3He proportional counters. Tests were performed at the FRANZ facility of the…
Detectors and Shieldings: Past and Future at LUNA
Chemseddine Ananna, Lucia Barbieri, Axel Boeltzig +11
Nuclear reactions are responsible for the chemical evolution of stars, galaxies and the Universe. Unfortunately, at temperatures of interest for nuclear astrophysics, the cross-sec…
SHADES -- Ne(,n)Mg reaction rate in the Gamow window
David Rapagnani, Chemseddine Ananna, Antonino Di Leva +4
Neutron capture reactions are the main contributors to the synthesis of the heavy elements through the s-process. Together with C(,n)16O, which has recently been measured…
Status and future directions for direct cross-section measurements of the 13C(a,n)16O reaction for astrophysics
L. Csedreki, Gy. Gyürky, D. Rapagnani +45
The 13C(a,n)16O reaction is the main neutron source of the s-process taking place in thermally pulsing AGB stars and it is one of the main candidate sources of neutrons for the i-p…
Improved direct measurement of low-energy resonances in the Ne(p,)Na reaction
R. S. Sidhu, F. Casaburo, E. Masha +57
In the nova temperature range, 0.1 GK 0.4 GK, several low-energy resonances dominate the Ne(p,)Na reaction rate, which is currently affected by large uncer…
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…
First direct measurement of the 64.5 keV resonance strength in O(p,)F reaction
R. M. Gesuè, G. F. Ciani, D. Piatti +50
The CNO cycle is one of the most important nuclear energy sources in stars. At temperatures of hydrostatic H-burning (20 MK T 80 MK) the O(p,)F reaction ra…
First measurement of the low-energy direct capture in 20Ne(p, γ)21Na and improved energy and strength of the Ecm = 368 keV resonance
E. Masha, L. Barbieri, J. Skowronski +48
The reaction is the slowest in the NeNa cycle and directly affects the abundances of the Ne and Na isotopes in a variety of astrophysical sites. Her…
New proton-capture rates on carbon isotopes and their impact on the astrophysical ratio
J. Skowronski, A. Boeltzig, G. F. Ciani +43
The ratio is a significant indicator of nucleosynthesis and mixing processes during hydrogen burning in stars. Its value mainly depends on the…
Underground Measurements of Nuclear Reaction Cross-Sections Relevant to AGB Stars
Chemseddine Ananna, Francesco Barile, Axel Boeltzig +11
Nuclear reaction cross sections are essential ingredients to predict the evolution of AGB stars and understand their impact on the chemical evolution of our Galaxy. Unfortunately,…
