Background in -ray detectors and carbon beam tests in the Felsenkeller shallow-underground accelerator laboratory
T. Szücs, D. Bemmerer, D. Degering +7
The relevant interaction energies for astrophysical radiative capture reactions are very low, much below the repulsive Coulomb barrier. This leads to low cross sections, low counti…
Nuclear Physics Mid Term Plan at LNGS
R. Buompane, F. Cavanna, C. Curceanu +59
The Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Gran Sasso (LNGS) is one of the largest underground physics laboratory, a very peculiar environment suited for ex…
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 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…
Improved -factor of the C(p,)N reaction at 330-740 keV and parameters of resonances at 448 keV and 551 keV
J. Skowronski, E. Masha, D. Piatti +23
The C(p,)N reaction is the second reaction of the CNO cycle. This cycle takes place in our Sun and fuels massive, Red, and Asymptotic Giant Branch stars. The $^{1…
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…
Measurement of the H()He S-factor at 265-1094keV
S. Turkat, S. Hammer, E. Masha +14
Recent astronomical data have provided the primordial deuterium abundance with percent precision. As a result, Big Bang nucleosynthesis may provide a constraint on the universal ba…
Improved -factor of the C(p,)N reaction at 320-620~keV and the 422~keV resonance
J. Skowronski, E. Masha, D. Piatti +17
The 12C(p,γ)13N reaction is the onset process of both the CNO and Hot CNO cycles that drive massive star, Red and Asymptotic Giant Branch star and novae nucleosynthesis. The 12C(p…
Photoexcitation of Ge
R. Schwengner, R. Massarczyk, K. Schmidt +15
The dipole strength of the nuclide Ge was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of energies of 7.8 and 12.3 MeV at the $…
Towards a comprehensive study of the 14N(p,g)15O astrophysical key reaction: Description of the experimental technique including novel target preparation
A. Compagnucci, A. Formicola, M. Campostrini +46
While the 14N(p,g)15O reaction plays a key role in the hydrogen-burning processes in various stellar conditions, its reaction rate is not known with sufficient precision. Therefore…
