The 63Ni(n,γ) cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were determined. Maxwellian averaged cross sections were calculated for thermal energies from kT=5–100 keV with uncertainties...

Neutron destruction reactions of the cosmic γ -ray emitter 26Al are of importance to determine the amount of 26Al ejected into our galaxy by supernova explosions and for 26Al production in asymptotic giant branch stars. We performed a new measurement of the 26Al(n, α) reaction up to 160-keV neutron energy at the neutron time-of-flight...

The 26 Al (n ,p) 26 Mg reaction is the key reaction impacting on the abundances of the cosmic y-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...

The cross section of the 62Ni(n,γ) reaction was measured with the time-of-flight technique at the neutron time-of-flight facility n-TOF at CERN. Capture kernels of 42 resonances were analyzed up to 200 keV neutron energy and Maxwellian averaged cross sections (MACS) from kT= 5-100 keV were calculated. With a total uncertainty of 4.5%, the...

The cross section of the reaction 197Au(n,γ) was measured with the time-of-flight technique at the n-TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C 6D6 (where D denotes 2H) liquid scintillators for the detection of prompt capture γ rays. The results with a total uncertainty of...

The 76 Ge ( n , γ ) 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. We have determined resonance capture kernels up to 52...

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. The 72Ge(n, γ) cross section has an important influence on production of isotopes between Ge...

The 72 Ge ( n , γ ) cross section was measured for neutron energies up to 300 keV at the neutron time-of-flight facility n _ TOF (CERN), Geneva, for the first time covering energies relevant to heavy-element synthesis in stars. The measurement was performed at the high-resolution beamline EAR-1, using an isotopically enriched 72 Ge O 2 ...

Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weak component of the slow neutron capture processes, which occurs in massive stars. The (n,γ) cross section on 70Ge, which is mainly produced in the s process, was measured at the neutron time-of-flight facility n_TOF at CERN. Resonance capture...
