Measurement of the prompt fission γ -rays from slow neutron-induced fission of 235 U with STEFF
(2024-03)
The average energy and multiplicity of prompt γ-rays from slow neutron-induced fission of 235U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from 11 ...
The Nuclear Reaction Network WinNet
(2023-10-11)
We present the state-of-the-art single-zone nuclear reaction network WinNet, which is capable of calculating the nucleosynthetic yields of a large variety of astrophysical environments and conditions. This ranges from the ...
74 Ge( n, γ ) cross section below 70 keV measured at n_TOF CERN
(2022-12-09)
Neutron capture reaction cross sections on 74Ge are of importance to determine 74Ge production during the astrophysical slow neutron capture process. We present new resonance data on 74Ge(n, γ) reactions below 70 keV neutron ...
Destruction of the cosmic γ -ray emitter Al 26 in massive stars: Study of the key Al 26 (n,p) reaction
(2021-08-30)
The Al26(n,p)Mg26 reaction is the key reaction impacting on the abundances of the cosmic γ-ray emitter Al26 produced in massive stars and impacts on the potential pollution of the early solar system with Al26 by asymptotic ...
Measurement of the 72Ge(n,γ) cross section over a wide neutron energy range at the CERN n_TOF facility
(2021-04-27)
The Ge72(n,γ) cross section was measured for neutron energies up to 300keV at the neutron time-of-flight facility n_TOF (CERN), Geneva, for the first time covering energies relevant to heavy-element synthesis in stars. The ...
Radiative neutron capture cross-section measurement of ge isotopes at n_TOF CERN facility and its importance for stellar nucleosynthesis
(2021-04-01)
This manuscript summarizes the results of radiative neutron capture cross-section measurements on two stable germanium isotopes, 70Ge and 73Ge. Experiments were performed at the n_TOF facility at CERN via the time-of-flight ...
Heavy elements nucleosynthesis on accreting white dwarfs : Building seeds for the p-process
(2020-10-01)
The origin of the proton-rich trans-iron isotopes in the Solar system is still uncertain. Single-degenerate thermonuclear supernovae (SNIa) with n-capture nucleosynthesis seeds assembled in the external layers of the ...
A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
(2020-07-21)
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called fission-tagging or fission-veto technique. For ...
Measurement of the Ge 70 (n,γ) cross section up to 300 keV at the CERN n-TOF facility
(2019-10-17)
Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weak component of the slow neutron capture processes, which occurs in massive stars. The (n,γ) cross section on Ge70, which ...
Uncertainties in νp-process nucleosynthesis from Monte Carlo variation of reaction rates
(2019-10)
It has been suggested that a νp-process can occur when hot, dense, and proton-rich matter is expanding within a strong flux of antineutrinos. In such an environment, proton-rich nuclides can be produced in sequences of ...
