Article
Restricted access - publisher's policy
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 C6D6 (where ...
• #### Constraints on the dipole photon strength for the odd uranium isotopes ﻿

(American Physical Society, 2022-02-01)
Article
Open Access
Nuclear level densities (NLDs) and photon strength functions (PSFs), also called ¿ -ray or radiation strength functions, represent average properties of the nucleus in the regime of excitation where individual levels and ...
• #### High-accuracy 233U(n, f ) cross-section measurement at the white-neutron source n TOF from near-thermal to 1 MeV neutron energy ﻿

(2009-10-08)
Article
Restricted access - publisher's policy
The 233U(n,f ) cross section has been measured at the white neutron source n TOF in a wide energy range with a dedicated fission ionization chamber. We report here the results from ∼30 meV to 1 MeV neutron energy. ...
• #### Measurement of the 72Ge(n,¿) cross section over a wide neutron energy range at the CERN n_TOF facility ﻿

(American Physical Society, 2021-04-01)
Article
Open Access
The 72 Ge ( n , ¿ ) 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 ...
• #### Neutron capture cross section measurements for nuclear astrophysics at CERN n_TOF ﻿

(2005-07)
Article
Restricted access - publisher's policy
A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton ...
• #### Neutron reactions and nuclear cosmo-chronology ﻿

(2007-07)
Article
Restricted access - publisher's policy
The -decay of 187Re (t1/2 = 42.3 Gyr) represents a suited cosmo-chronometer for the age of the r-process abundances, since the radiogenic part of the daughter isotope 187Os is defined by the difference between the solar ...
• #### Present status and future programs of the n-TOF experiment ﻿

(2011)
Conference report
Open Access
The neutron time-of-flight facility n_TOF at CERN, Switzerland, operational since 2001, delivers neutrons using the Proton Synchrotron (PS) 20 GeV/c proton beam impinging on a lead spallation target. The facility combines ...

(2006-11)
Article
Restricted access - publisher's policy
The radiative neutron capture cross section of 207Pb has been measured at the CERN neutron time of flight installation n TOF using the pulse height weighting technique in the resolved energy region. The measurement has ...
• #### Status and outlook of the neutron time-of-flight facility n_TOF at CERN ﻿

(2007-08)
Article
Restricted access - publisher's policy
The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight ...
