Radiative neutron capture cross section of $^{242}$Pu measured at n_TOF-EAR1 in the unresolved resonance region up to 600 keV / n_TOF Collaboration
The design of fast reactors burning MOX fuels requires accurate capture and fission cross sections. [...]

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.

$^{74}$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. [...]

$^{7}$ Be(n,p)$^{7}$ Li Cross Section Measurement for the Cosmological Lithium Problem at the n $\_$ TOF Facility at CERN / n_TOF Collaboration
One of the most puzzling problems in Nuclear Astrophysics is the “Cosmological Lithium Problem”, i.e the discrepancy between the primordial abundance of$^{7}$ Li observed in metal poor halo stars (Asplund et al. in Astrophys J 644:229–259, 2006, [1]), and the one predicted by Big Bang Nucleosynthesis (BBN).

Radiative Neutron Capture Cross-Section Measurement of Ge Isotopes at n_TOF CERN Facility and Its Importance for Stellar Nucleosynthesis / n_TOF Collaboration
This manuscript summarizes the results of radiative neutron capture cross-section measurements on two stable germanium isotopes, $^{70}$Ge and $^{73}$Ge. Experiments were performed at the n_TOF facility at CERN via the time-of-flight technique, over a wide neutron energy range, for all stable germanium isotopes (70,72,73,74, and 76). [...]

$^{92}$Zr($n,\gamma$) and ($n$,tot) measurements at the GELINA and n_TOF facilities / n_TOF Collaboration
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 magic number N = 50 and its position at the matching region between the weak and main slow processes. Purpose: In parallel with recent improved astronomical data, the extraction of accurate Maxwellian averaged cross sections (MACSs) derived from a more complete and accurate set of resonance parameters should allow for a better understanding of the stellar conditions at which nucleosynthesis takes place. Methods: Transmission and capture cross section measurements using enriched 92Zr metallic samples were performed at the time-of flight facilities GELINA of JRC-Geel (BE) and n_TOF of CERN (CH). [...]

High accuracy, high resolution $^{235}$U(n,f) cross section from n_TOF (CERN) from 18 meV to 10 keV / n_TOF Collaboration
The 235U(n,f) cross section was measured in a wide energy range (25 meV - 170 keV) at the n_TOF facility at CERN, relative to 6Li(n,t) and 10B(n,alpha) standard reactions, with high resolution and accuracy, with a setup based on a stack of six samples and six silicon detectors placed in the neutron beam. In this paper we report on the results in the region between thermal and 10 keV neutron energy. [...]

Measurement of the $^{76}\mathrm{Ge}(n,{\gamma})$ cross section at the n_TOF facility at CERN / n_TOF Collaboration
The $^{76}\mathrm{Ge}(n,{\gamma})$ reaction has been measured at the n_TOF facility at CERN via the time-of-flight technique. Neutron capture cross sections on $^{76}$Ge are of interest to a variety of low-background experiments, such as neutrinoless double β decay searches, and to nuclear astrophysics. [...]

Destruction of the cosmic γ-ray emitter $^{26}$Al in massive stars: Study of the key $^{26}$Al$(n,\alpha)$ reaction / n_TOF Collaboration
Neutron destruction reactions of the cosmic $\gamma$-ray emitter $^{26}$Al are of importance to determine the amount of $^{26}$Al ejected into our galaxy by supernova explosions and for 26 Al production in asymptotic giant branch stars. We performed a new measurement of the $^{26}$Al$(n, \alpha)$ reaction up to 160-keV neutron energy at the neutron time-of-flight facilities n_TOF at CERN and GELINA at EC-JRC. [...]
