High resolution $^{80}$Se(n,γ) cross section measurement at CERN n_TOF / n_TOF Collaboration
Neutron capture cross section measurements of isotopes close to s-process branching-points are of fundamental importance for the understanding of this nucleosynthesis mechanism through which about 50% of the elements heavier than iron are produced. We present in this contribution the results corresponding to the high resolution measurement, for first time ever, of the $^{80}$Se(n, γ) cross section, in which 98 resonances never measured before have been reported. [...]

A new measurement of the $^{235}$U(n,f) fission cross section was carried out at n_TOF. The experiment covered the neutron energy range from 10 MeV up to 500 MeV, and it used the 1H(n,n) cross section as normalization for the neutron fluence measurement. [...]

Measurement of the $^{235}$U(n,f) cross section relative to the $^{10}$B(n,α) reaction with Micromegas detectors at the CERN n_TOF facility: First results / n_TOF Collaboration
Neutron cross section measurements are often made relative to a neutron cross section standard. Thus, the accuracy of the neutron standards determines the best possible accuracy of the neutron measurements. [...]

Characterization of a detector setup for the measurement of the $^{235}$U(n,f) cross section relative to n-p scattering up to 500 MeV at the n_TOF facility at CERN / Manna, A (U.

The measurement of the $^{235}$U(n,f) reaction cross section in the neutron energy region 10 MeV to 500 MeV was carried out at the CERN n_TOF facility. The experimental campaign, completed in 2018, provided precise and accurate data on the fission reaction relative to neutron-proton elastic scattering. [...]

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 Ce140(n,γ) Cross Section at n_TOF and Its Astrophysical Implications for the Chemical Evolution of the Universe / n_TOF Collaboration
Ce140(n,γ) is a key reaction for slow neutron-capture (s-process) nucleosynthesis due to being a bottleneck in the reaction flow. For this reason, it was measured with high accuracy (uncertainty ≈5%) at the n_TOF facility, with an unprecedented combination of a high purity sample and low neutron-sensitivity detectors. [...]

New insights on fission of $^{235}$U induced by high energy neutrons / n_TOF Collaboration
The $^{235}$U(n,f) reaction cross section was measured relative to neutron-proton elastic scattering for the first time in the energy region from 10 MeV to 440 MeV at the CERN n_TOF facility, extending the upper limit of the only previous measurement in the literature by more than 200 MeV. Two independent detection systems were used simultaneously to extract the fission cross section. [...]

The neutron-induced fission cross section of Th230 has been measured at the neutron time-of-flight facility n_TOF located at CERN. The experiment was performed at the experimental area EAR-1 with a neutron flight path of 185 m, using Micromegas detectors for the detection of the fission fragments. [...]

First $^{80}$Se(n,$\gamma$) cross section measurement with high resolution in the full stellar energy range 1 eV - 100 keV and its astrophysical implications for the s-process / n_TOF Collaboration
Most elements heavier than iron have been generated in the stellar media by means of neutron capture reactions, approximately half are produced by the slow neutron capture or s-process. Radiative neutron capture cross section measurements are of fundamental importance for the study of this mechanism. [...]

We demonstrate a new technique for obtaining fission data for nuclei away from $\beta$-stability. These types of data are pertinent to the astrophysical \textit{r-}process, crucial to a complete understanding of the origin of the heavy elements, and for developing a predictive model of fission.
