Precision study of ground state capture in the 14N(p,gamma)15O reaction
M. Marta, A. Formicola, Gy. Gyurky +28
The rate of the hydrogen-burning carbon-nitrogen-oxygen (CNO) cycle is controlled by the slowest process, 14N(p,gamma)15O, which proceeds by capture to the ground and several excit…
70Ge(p,gamma)71As and 76Ge(p,n)76As cross sections for the astrophysical p process: sensitivity of the optical proton potential at low energies
G. G. Kiss, Gy. Gyurky, Z. Elekes +4
The cross sections of the 70Ge(p,gamma)71As and 76Ge(p,n)76As reactions have been measured with the activation method in the Gamow window for the astrophysical p process. The exper…
Measurement of 25Mg(p; gamma)26Al resonance strengths via gamma spectrometry
A. Formicola, A. Best, G. Imbriani +28
The COMPTEL instrument performed the first mapping of the 1.809 MeV photons in the Galaxy, triggering considerable interest in determing the sources of interstellar 26Al. The predi…
Ground state capture in N(p,)O studied above the 259 keV resonance at LUNA
H. P. Trautvetter, D. Bemmerer, R. Bonetti +29
We report on a new measurement of N(p,)O for the ground state capture transition at = 360, 380 and 400 keV, using the 400 kV LUNA accelerator. The true coinc…
Comparison of the LUNA 3He(alpha,gamma)7Be activation results with earlier measurements and model calculations
Gy. Gyurky, D. Bemmerer, F. Confortola +27
Recently, the LUNA collaboration has carried out a high precision measurement on the 3He(alpha,gamma)7Be reaction cross section with both activation and on-line gamma-detection met…
Photon-induced Nucleosynthesis: Current Problems and Experimental Approaches
P. Mohr, Zs. Fulop, H. Utsunomiya
Photon-induced reactions play a key role in the nucleosynthesis of rare neutron-deficient p-nuclei. The paper focuses on (gamma,alpha), (gamma,p), and (gamma,n) reactions which def…
