Detector characterization for a new C+C reaction study at LUNA
R. M. Gesùè, S. Turkat, J. SkowroÅski +50
The C+C fusion reaction plays a crucial role in stellar evolution, including the occurrence of supernova explosions, and in the synthesis of the chemical elements. Ho…
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…
Advances in Radiative Capture Studies at LUNA with a Segmented BGO Detector
Jakub Skowronski, Riccardo Maria Gesuè, Axel Boeltzig +43
Studies of charged-particle reactions for low-energy nuclear astrophysics require high sensitivity, which can be achieved by means of detection setups with high efficiency and low…
Low-energy Cross Section Measurements of Deep Underground at LUNA
Jakub Skowronski, Axel Boeltzig
The reaction cross section is currently under investigation in the low-background environment of the Laboratory for Underground Nuclear…
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…
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…
