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. [...]

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. [...]

Destruction of the cosmic $\gamma$-ray emitter $^{26}$Al in massive stars: Study of the key $^{26}$Al$(n,p)$ reaction / n_TOF Collaboration
The  $^{26}$Al$(n,p)$ $^{26}$Mg reaction is the key reaction impacting on the abundances of the cosmic  γ -ray emitter  $^{26}$Al  produced in massive stars and impacts on the potential pollution of the early solar system with  $^{26}$Al  by asymptotic giant branch stars. We performed a measurement of the  $^{26}$Al$(n,p)$ $^{26}$Mg  cross section at the high-flux beam line EAR-2 at the n_TOF facility (CERN). [...]

Preparation and characterization of  $^{33}$S samples for  $^{33}$S(n,$\alpha$) $^{30}$Si cross-section measurements at the n_TOF facility at CERN / Praena, J (Granada U.) ; Ferrer, F J (CNA, Seville) ; Vollenberg, W (CERN) ; Sabaté-Gilarte, M (Seville U. ; CERN) ; Fernández, B (CNA, Seville ; Seville U.) ; García-López, J (CNA, Seville ; Seville U.) ; Porras, I (Granada U.) ; Quesada, J M (Seville U.) ; Altstadt, S (Goethe U., Frankfurt (main)) ; Andrzejewski, J (Lodz U.) et al. /n_TOF
Thin  33 S samples for the study of the  33 S(n, α ) 30 Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of  33 S powder onto a dedicated substrate made of kapton covered with thin layers of copper, chromium and titanium. This method has provided for the first time bare sulfur samples a few centimeters in diameter. [...]
