Neutron measurements for advanced nuclear systems : The n_TOF project at CERN
(2011-12-15)
A few years ago, the neutron time-of-flight facility n_TOF was built at CERN to address some of the urgent needs of high-accuracy nuclear data for Accelerator Driven Systems and other advanced nuclear energy systems, as ...
Measurement of the neutron-induced fission cross-section of Am-243 relative to U-235 from 0.5 to 20 MeV
(2011-12)
The ratio of the neutron-induced fission cross-sections of Am-243 and U-235 was measured in the energy range from 0.5 to 20 MeV with uncertainties of approximate to 4%. The experiment was performed at the CERN n_TOF facility ...
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 ...
Determination of Pr-141(alpha, n)Pm-144 cross sections at energies of relevance for the astrophysical p process using the gamma gamma coincidence method
(2011-10-19)
The reaction Pr-141(alpha, n)Pm-144 was investigated between E-alpha = 11 MeV and 15 MeV with the activation method using the gamma gamma coincidence method with a segmented clover-type high-purity Germanium (HPGe) detector. ...
Activation method combined with characteristic X-ray counting : A possibility to measure (alpha, gamma) cross sections on heavy p-nuclei
(2011-10-01)
For an improved modeling of the astrophysical nucleosynthesis of p-nuclei, low energy cross section data of alpha-induced reactions on heavy isotopes are needed. Technical difficulties hamper the experimental determination ...
Opportunities to constrain astrophysical reaction rates for the s-process via determination of the ground-state cross-sections
(2011-09-10)
Modern models of s-process nucleosynthesis in stars require stellar reaction rates of high precision. Most neutron-capture cross-sections in the s-process have been measured, and for an increasing number of reactions the ...
Neutron Capture Measurements on Minor Actinides at the n_TOF Facility at CERN : Past, Present and Future
(2011-08-11)
The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity studies and reports [1-3] have ...

(2011-08-11)
Neutron-induced fission cross-sections of minor actinides have been measured using the n_TOF white neutron source at CERN. Geneva, as part of a large experimental program aiming at collecting new data relevant for nuclear ...
Np-237(n,f) Cross Section : New Data and Present Status
(2011-08-11)
In this document, we present the final result obtained at the n_TOF experiment; for the neutron-induced fission cross section of the Np-237, from the fission threshold up to 1 GeV. The method applied to get tins result is ...
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 ...
