Fission program at n_TOF
(EDP Sciences, 2019)
Since its start in 2001 the n_TOF collaboration developed a measurement program on fission, in view of advanced fuels in new generation reactors. A special effort was made on measurement of cross sections of actinides, ...

Neutron capture cross section measurements of 241Am at the n_TOF facility
(EDP Sciences, 2020)
Neutron capture on 241Am plays an important role in the nuclear energy production and also provides valuable information for the improvement of nuclear models and the statistical interpretation of the nuclear properties. ...

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 ...

Experimental setup and procedure for the measurement of the 7Be(n,α)α reaction at n_TOF
(Elsevier, 2016-09-11)
The newly built second experimental area EAR2 of the n_TOF spallation neutron source at CERN allows to perform (n, charged particles) experiments on short-lived highly radioactive targets. This paper describes a detection ...

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 ...

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 ...

92 Zr ( n , γ ) and ( n ,tot) measurements at the GELINA and n_TOF facilities
(American Physical Society, 2022)
Background: Stellar nucleosynthesis of elements heavier than iron is driven by neutron capture processes. 92Zr is positioned at a strategic point along the slow nucleosynthesis path, given its proximity to the neutron ...

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 ...
