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 the240Pu(n,f) cross-section at the CERN n-TOF facility: First results from EAR-2 ﻿

(2015)
Conference report
Open Access
The accurate knowledge of neutron cross-sections of a variety of plutonium isotopes and other minor actinides, such as neptunium, americium and curium, is crucial for feasibility and performance studies of advanced nuclear ...
• #### 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 ...
• #### Neutron-induced fission cross section of Np-237 in the keV to MeV range at the CERN n_TOF facility ﻿

(2016-03-17)
Article
Open Access
The neutron-induced fission cross section of 237Np was experimentally determined at the high-resolution and high-intensity facility n TOF, at CERN, in the energy range 100 keV to 9 MeV, using the 235U(n,f ) and 238U(n,f ...
• #### Nuclear physics for the Re/Os clock ﻿

(2008-01)
Article
Restricted access - publisher's policy
Dating the age of the universe by the β-decay of 187Re (t1/2 = 41.2 Gyr) requires the accurate assessment of the s-process reaction flow. The daughter nucleus 187Os as well as its immediate s-only neighbor 186Os are ...

(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 ﻿

(American Institute of Physics (AIP), 2011)
Conference report
Restricted access - publisher's policy
The 237Np(n,f) cross sections have been measured at the n-TOF facility relative to the 235U and 238U fission cross sections. The n-TOF spallation neutron source at CERN is characterized by a high intensity flux, an excellent ...
