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 α ratio and (n, γ) cross section of 235U from 0.2 to 200 eV at n_TOF
(American Physical Society, 2020)
We measured the neutron capture-to-fission cross-section ratio (α ratio) and the capture cross section of 235U between 0.2 and 200 eV at the n_TOF facility at CERN. The simultaneous measurement of neutron-induced capture ...

Performance of the neutron time-of-flight facility n_TOF at CERN
(Springer Verlag, 2013)
The neutron time-of-flight facility n_TOF features a white neutron source produced by spallation through 20 GeV/c protons impinging on a lead target. The facility, aiming primarily at the measurement of neutron-induced ...

Measurement of the 244Cm and 246Cm neutron-induced capture cross sections at the n_TOF facility
(EDP Sciences, 2019)
The neutron capture reactions of the 244Cm and 246Cm isotopes open the path for the formation of heavier Cm isotopes and heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the ...
