Results of the $^{244}$Cm, $^{246}$Cm and $^{248}$Cm neutron-induced capture cross sections measurements at EAR1 and EAR2 of the n_TOF facility / nTOF Collaboration
Accurate neutron capture cross section data for minor actinides (MAs) are required to estimate the production and transmutation rates of MAs in light water reactors, critical fast reactors like Gen-IV systems, and other innovative reactor systems such as accelerator driven systems (ADS). In particular, 244Cm, 246Cm and 248Cm play a role in the transport, storage and transmutation of the nuclear waste of the current nuclear reactors, due to the contribution of these isotopes to the radiotoxicity, neutron emission, and decay heat in the spent nuclear fuel.

Measurement of the $^{241}$Am(n,γ) cross section at the n_TOF facility at CERN / n_TOF Collaboration
The neutron capture cross section of $^{241}$Am is an important quantity for nuclear energy production and fuel cycle scenarios. Several measurements have been performed in recent years with the aim to reduce existing uncertainties in evaluated data. [...]

The Stellar $^{72}$Ge(n, γ) Cross Section for weak s-process: A First Measurement at n_TOF / Dietz, M (Edinburgh U. ; Braunschweig, Phys. Tech. Bund.) ; Lederer-Woods, C (Edinburgh U.) ; Tattersall, A (Edinburgh U.) ; Battino, U (Edinburgh U.) ; Gunsing, F (IRFU, Saclay ; CERN) ; Heinitz, S (PSI, Villigen) ; Lerendegui-Marco, J (Seville U.) ; Krtička, M (Charles U. ; Seville U.) ; Reifarth, R (Frankfurt U.) ; Valenta, S (Charles U.) et al.
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 input for s-process studies. [...]

Shedding Light on the Origin of Pb204, the Heaviest s-Process–Only Isotope in the Solar System / n_TOF Collaboration
Asymptotic giant branch stars are responsible for the production of most of the heavy isotopes beyond Sr observed in the solar system. Among them, isotopes shielded from the r-process contribution by their stable isobars are defined as s-only nuclei. [...]

Measurement of the prompt fission $\gamma $-rays from slow neutron-induced fission of $^{235}$U with STEFF / n_TOF Collaboration
The average energy and multiplicity of prompt $\gamma $-rays from slow neutron-induced fission of $^{235}$U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from 11 NaI scintillators were corrected for multiple $\gamma $-ray interactions, prompt fission neutrons and background counts before being deconvolved to estimate the emitted spectrum of prompt fission $\gamma $-rays.

Measurement of the Se77(n,γ) cross section up to 200 keV at the n_TOF facility at CERN / n_TOF Collaboration
The Se77(n,γ) reaction is of importance for Se77 abundance during the slow neutron capture process in massive stars. We have performed a new measurement of the Se77 radiative neutron capture cross section at the Neutron Time-of-Flight facility at CERN. [...]

Neutron-induced fission cross sections of Th232 and U233 up to 1 GeV using parallel plate avalanche counters at the CERN n_TOF facility / n_TOF Collaboration
The neutron-induced fission cross sections of Th232 and U233 were measured relative to U235 in a wide neutron energy range up to 1 GeV (and from fission threshold in the case of Th232, and from 0.7 eV in case of U233), using the white-spectrum neutron source at the CERN Neutron Time-of-Flight (n_TOF) facility. Parallel plate avalanche counters (PPACs) were used, installed at the Experimental Area 1 (EAR1), which is located at 185 m from the neutron spallation target. [...]

Measurement of the $^{14}$N(n,p)$^{14}$C cross section at the CERN n_TOF facility from sub-thermal energy to 800 keV / n_TOF Collaboration
Background: The $^{14}$N(n,p)$^{14}$C reaction is of interest in neutron capture therapy, where nitrogen-related dose is the main component due to low-energy neutrons, and in astrophysics, where 14N acts as a neutron poison in the s-process. Several discrepancies remain between the existing data obtained in partial energy ranges: thermal energy, keV region and resonance region. [...]

$^{74}$Ge($n,\gamma $) cross section below 70 keV measured at n_TOF CERN / n_TOF Collaboration
Neutron capture reaction cross sections on $^{74}$Ge are of importance to determine $^{74}$Ge production during the astrophysical slow neutron capture process. We present new resonance data on $^{74}$Ge($n,\gamma $) reactions below 70 keV neutron energy. [...]
