Measurement of the 76 Ge ( n , γ ) cross section at the n_TOF facility at CERN
(American Physical Society, 2021)
The 76 Ge ( n , γ ) reaction has been measured at the n_TOF facility at CERN via the time-of-flight technique. Neutron capture cross sections on 76 Ge are of interest to a variety of low-background experiments, ...

80Se(n,?) cross-section measurement at CERN n TOF
(Institute of Physics Publishing, 2020)
Radiative neutron capture cross section measurements are of fundamental importance for the study of the slow neutron capture (s-) process of nucleosynthesis. This mechanism is responsible for the formation of most elements ...

Preliminary results on the 233U capture cross section and alpha ratio measured at n_TOF (CERN) with the fission tagging technique
(EDP Sciences, 2019)
233U is of key importance among the fissile nuclei in the Th-U fuel cycle. A particularity of 233U is its small neutron capture cross-section, which is on average about one order of magnitude lower than the fission ...

The Nuclear Astrophysics program at n_TOF (CERN
(EDP Sciences: EPJ Open Access, 2017)
An important experimental program on Nuclear Astrophysics is being carried out at the n_TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis. Several neutron capture ...

New reaction rates for the destruction of 7Be during big bang nucleosynthesis measured at CERN/n_TOF and their implications on the cosmological lithium problem
(EDP Sciences, 2020)
New measurements of the 7Be(n,α)4He and 7Be(n,p)7Li reaction cross sections from thermal to keV neutron energies have been recently performed at CERN/n_TOF. Based on the new experimental results, astrophysical reaction ...

Study of the photon strength functions and level density in the gamma decay of the n + 234U reaction
(EDP Sciences, 2019)
The accurate calculations of neutron-induced reaction cross sections are relevant for many nuclear applications. The photon strength functions and nuclear level densities are essential inputs for such calculations. These ...

Destruction of the cosmic γ -ray emitter 26 Al in massive stars: Study of the key 26 Al ( n , α ) reaction
(American Physical Society, 2021)
Neutron destruction reactions of the cosmic γ -ray emitter 26Al are of importance to determine the amount of 26Al ejected into our galaxy by supernova explosions and for 26Al production in asymptotic giant branch stars. ...

Measurement of the 72 Ge ( n , γ ) cross section over a wide neutron energy range at the CERN n_TOF facility
(American Physical Society, 2021)
The 72 Ge ( n , γ ) cross section was measured for neutron energies up to 300 keV at the neutron time-of-flight facility n _ TOF (CERN), Geneva, for the first time covering energies relevant to ...

Constraints on the dipole photon strength for the odd uranium isotopes
(American Physical Society, 2022)
Background: The photon strength functions (PSFs) and nuclear level density (NLD) are key ingredients for calculation of the photon interaction with nuclei, in particular the reaction cross sections. These cross sections ...

Measurement of the 70Ge(n,γ) cross section up to 300 keV at the CERN n_TOF facility
(American Physical Society, 2019)
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 70Ge, which ...
