Improved Mo neutron resonance parameters from neutron capture and transmission measurements at n_TOF and GELINA
R. Mucciola, S. Cristallo, S. Kopecky +140
We report high-resolution measurements of the cross section in the neutron energy range from a few eV up to about 250 keV, performe…
First Nb() Measurement: Constraining the Nucleosynthetic Origin of Mo in Presolar Grains
J. Balibrea-Correa, J. Lerendegui-Marco, C. Domingo-Pardo +136
Isotopic measurements of presolar silicon carbide grains from dying stars have revealed a puzzling overabundance of Mo that stellar nucleosynthesis models have failed to rep…
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…
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…
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 unce…
