First Measurement of 72Ge(n, γ) at n_TOF
(EDP Sciences, 2018)
The slow neutron capture process (s-process) is responsible for producing about half of the elemental abundances heavier than iron in the universe. Neutron capture cross sections on stable isotopes are a key nuclear physics ...

Measurement of the 154Gd(n,γ) cross section and its astrophysical implications
(Elsevier, 2020)
The neutron capture cross section of 154Gd was measured from 1 eV to 300 keV in the experimental area located 185 m from the CERN n_TOF neutron spallation source, using a metallic sample of gadolinium, enriched to 67% ...

Measurement and analysis of 155,157Gd(n,γ) from thermal energy to 1 keV
(EDP Sciences, 2020)
We have measured the capture cross section of the 155Gd and 157Gd isotopes between 0.025 eV and 1 keV. The capture events were recorded by an array of 4 C6D6 detectors, and the capture yield was deduced exploiting the total ...

Preliminary results on the 233U α-ratio measurement at n_TOF
(EDP Sciences, 2020)
233U is the fissile nuclei in the Th-U fuel cycle with a particularily small neutron capture cross setion which is on average about one order of magnitude lower than its fission cross section. Hence, the measurement of the ...

Accurate measurement of the standard 235U(n,f) cross section from thermal to 170 keV neutron energy
(EDP Sciences, 2020)
An accurate measurement of the 235U(n,f) cross section from thermal to 170 keV of neutron energy has recently been performed at n_TOF facility at CERN using 6Li(n,t)4He and 10B(n,α)7Li as references. This measurement has ...

Study of photon strength functions of 241Pu and 245Cm from neutron capture measurements
(EDP Sciences, 2020)
We have measured the γ-rays following neutron capture on 240Pu and 244 Cm at the n_TOF facility at CERN with the Total Absorption Calorimeter (TAC) and with C6D6 organic scintillators. The TAC is made of 40 BaF2 crystals ...

Monte Carlo simulations and n-p differential scattering data measured with Proton Recoil Telescopes
(EDP Sciences, 2020)
The neutron-induced fission cross section of 235U, a standard at thermal energy and between 0.15 MeV and 200 MeV, plays a crucial role in nuclear technology applications. The long-standing need of improving cross section ...
