Measurement of the prompt fission γ -rays from slow neutron-induced fission of 235 U with STEFF
(2024-03)
The average energy and multiplicity of prompt γ-rays from slow neutron-induced fission of 235U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from 11 ...
First 80Se(n,γ) cross section measurement with high resolution in the full stellar energy range 1 eV - 100 keV and its astrophysical implications for the s-process
(2022-02-24)
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 ...
Destruction of the cosmic γ -ray emitter Al 26 in massive stars: Study of the key Al 26 (n,p) reaction
(2021-08-30)
The Al26(n,p)Mg26 reaction is the key reaction impacting on the abundances of the cosmic γ-ray emitter Al26 produced in massive stars and impacts on the potential pollution of the early solar system with Al26 by asymptotic ...
Measurement of the 72Ge(n,γ) cross section over a wide neutron energy range at the CERN n_TOF facility
(2021-04-27)
The Ge72(n,γ) cross section was measured for neutron energies up to 300keV 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 ...
A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
(2020-07-21)
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called fission-tagging or fission-veto technique. For ...
Measurement of the 235U(n, f) cross section relative to the 6Li(n, t) and 10B(n, α) standards from thermal to 170 keV neutron energy range at n_TOF
(2019-07-01)
The 235U(n, f) cross section was measured at n_TOF relative to 6Li(n, t) and 10B(n,α) , with high resolution (L= 183. 49 (2) m) and in a wide energy range (25meV-170keV) with 1.5% systematic uncertainty, making use of a ...
Experimental setup and procedure for the measurement of the 7Be(n,p)7Li reaction at n_TOF
(2018-04-11)
Following the completion of the second neutron beam line and the related experimental area (EAR2) at the n_TOF spallation neutron source at CERN, several experiments were planned and performed. The high instantaneous neutron ...
