Neutron-induced fission cross section measurement of U-233, Am-241 and Am-243 in the energy range 0.5 MeV
(2012-10)
Neutron-induced fission cross section measurements of U-233, Am-243 and Am-241 relative to U-235 have been carried out at the neutron time-of-flight facility n_TOF at CERN. A fast ionization chamber has been employed. All ...
Measurement and resonance analysis of the Np-237 neutron capture cross section
(2012-04-20)
The neutron capture cross section of Np-237 was measured between 0.7 and 500 eV at the CERN n_TOF facility using the 4 pi BaF2 Total Absorption Calorimeter. The experimental capture yield was extracted minimizing all the ...
Resonance neutron-capture cross sections of stable magnesium isotopes and their astrophysical implications
(2012-04-20)
We have measured the neutron capture cross sections of the stable magnesium isotopes Mg-24,Mg-25,Mg-26 in the energy range of interest to the s process using the neutron time-of-flight facility n_TOF at CERN. Capture events ...
Neutron-induced fission cross section of Cm-245 : New results from data taken at the time-of-flight facility n_TOF
(2012-03-29)
The neutron-induced fission cross section of Cm-245 was measured at n_TOF in a wide energy range and with high resolution. The energy dependence, measured in a single measurement from 30 meV to 1 MeV neutron energy, has ...
Measurement of the U-236(n, f) cross section from 170 meV to 2 MeV at the CERN n_TOF facility
(2011-10-31)
The neutron-induced fission cross section of U-236 was measured at the neutron Time-of-Flight (n_TOF) facility at CERN relative to the standard U-235(n, f) cross section for neutron energies ranging from above thermal to ...
Study of Photon Strength Function of Actinides : the Case of U-235, Np-238 and Pu-241
(2011-08-11)
The decay from excited levels in medium and heavy nuclei can be described in a statistical approach by means of Photon Strength Functions and Level Density distributions. The study of electromagnetic cascades following ...
Neutron-induced fission cross section of Pb-nat and Bi-209 from threshold to 1 GeV : An improved parametrization
(2011-04-28)
Neutron-induced fission cross sections for Pb-nat and Bi-209 were measured with a white-spectrum neutron source at the CERN Neutron Time-of-Flight (n_TOF) facility. The experiment, using neutrons from threshold up to 1 ...
The Np-237(n,f) cross section at the CERN n-TOF facility
(American Institute of Physics (AIP), 2011)
The Np-237(n,f) cross sections have been measured at the n-TOF facility relative to the U-235 and U-238 fission cross sections. The n-TOF spallation neutron source at CERN is characterized by a high intensity flux, an ...
The Zr-92(n,gamma) reaction and its implications for stellar nucleosynthesis
(2010-05)
Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear ...
Au-197(n,gamma) cross section in the resonance region
(2010-04)
The (n,gamma) cross section of Au-197 has been measured at n_TOF in the resolved resonance region, up to 5 keV, with the aim of improving the accuracy in an energy range where it is not yet considered standard. The ...
