Neutron-induced fission cross section of U-234 and Np-237 measured at the CERN Neutron Time-of-Flight (n_TOF) facility
(2010-09-08)
A high-resolution measurement of the neutron-induced fission cross section of U-234 and Np-237 has been performed at the CERN Neutron Time-of-Flight facility. The cross sections have been determined in a wide energy range ...
Neutron resonance spectroscopy at n_TOF at CERN
(EDP Sciences, 2008)
Neutron resonance spectroscopy plays an important role in the investigation of neutron induced reaction cross sections and nuclear structure in the MeV excitation range. Neutron time-of-flight facilities are the most used ...
Simultaneous measurement of the neutron capture and fission yields of (233)U
(EDP Sciences, 2008)
We have measured the neutron capture and fission cross section of 233 U at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4 pi BaF(2) ...
Improved lead and bismuth (n,gamma) cross sections and their astrophysical impact
(EDP Sciences, 2008)
A series of (n,gamma) neutron capture measurements on the lead isotopes and bismuth have been carried Out at the CERN n_TOF installation in the neutron energy range from 1 eV up to 1 MeV. At n_TOF, contaminations due to ...
Nuclear physics for the Re/Os clock
(2008-01)
Dating the age of the universe by the beta-decay of (187)Re (t(1/2) = 41.2 Gyr) requires the accurate assessment of the s-process reaction flow. The daughter nucleus (187)Os as well as its immediate s-only neighbor (186)Os ...
The (234)U neutron capture cross section measurement at the n_TOF facility
(EDP Sciences, 2008)
The neutron capture cross-section of (234)U has been measured for energies from thermal up to the keV region in the neutron time-of-flight facility n_TOF, based on a spallation source located at CERN. A 4 pi BaF(2) array ...
