Measurement of the U 238 (n,γ) cross section up to 80 keV with the total absorption calorimeter at the CERN n-TOF facility
(American Physical Society, 2017)
The radiative capture cross section of a highly pure (99.999%), 6.125(2) grams and 9.56(5)× 10−4 atoms/barn areal density 238U sample has been measured with the Total Absorption Calorimeter (TAC) in the 185 m flight path ...

Measurement of the 242Pu(n, γ) cross section from thermal to 500 keV at the Budapest research reactor and CERN n_TOF-EAR1 facilities
(EDP Sciences, 2020)
The design and operation of innovative nuclear systems requires a better knowledge of the capture and fission cross sections of the Pu isotopes. For the case of capture on 242Pu, a reduction of the uncertainty in the fast ...

The 154Gd neutron capture cross section measured at the n_TOF facility and its astrophysical implications
(EDP Sciences, 2020)
The (n, γ) cross sections of the gadolinium isotopes play an important role in the study of the stellar nucleosynthesis. In particular, among the isotopes heavier than Fe, 154Gd together with 152Gd have the peculiarity to ...

Measurement of the energy-differential cross-section of the 12C(n,p)12B and 12C(n,d)11B reactions at the n_TOF facility at CERN
(EDP Sciences, 2020)
Although the 12C(n,p)12B and 12C(n,d)11B reactions are of interest in several fields of basic and applied Nuclear Physics the present knowledge of these two cross-sections is far from being accurate and reliable, with both ...
