First determination of ß -delayed multiple neutron emission beyond A=100 through direct neutron measurement: the P2n value of Sb 136
(American Physical Society (APS), 2018-09-10)
Article
Accés obertBackground: ß-delayed multiple neutron emission has been observed for some nuclei with A=100, being the 100Rb the heaviest ß2n emitter measured to date. So far, only 25P2n values have been determined for the ˜300 nuclei ... -
7Be(n , p)7Li reaction and the cosmological lithium problem: measurement of the cross section in a wide energy range at n_TOF at CERN
(American Institute of Physics (AIP), 2018-07-24)
Article
Accés obertWe report on the measurement of the 7Be(n,p)7Li cross section from thermal to approximately 325 keV neutron energy, performed in the high-flux experimental area (EAR2) of the n_TOF facility at CERN. This reaction plays a ... -
PVST, a tool to assess the power to volume scaling distortions associated to code simulations
(2018-06-01)
Article
Accés restringit per política de l'editorialSystem codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. In order to assess the safety of a particular power plant, in addition to the validation and veri cation of the code, ... -
The “Beta-Delayed Neutrons at RIKEN” project (BRIKEN): conquering the most exotic beta-delayed neutron-emitters
(2018-01-02)
Article
Accés obertAmong the main missions of modern radioactive isotope facilities is the exploration of properties of yet unknown isotopes on the neutron-rich side of the chart of nuclides. However, going more neutron-rich also means that ... -
Development of the safety code AINA for the European DEMO designs
(2018-04-30)
Article
Accés restringit per política de l'editorialIn order to evaluate plasma evolution and in-vessel components strains, a safety code called AINA has been developing during the last ten years for different fusion reactors designs. This work describes the new AINA code ... -
Measurement and resonance analysis of the 33S (n, alpha) 30Si cross section at the CERN n_TOF facility in the energy region from 10 to 300 keV
(AMER PHYSICAL SOC, 2018-06-04)
Article
Accés obertThe 33S(n,a)30Si cross section has been measured at the neutron time-of-flight (n_TOF) facility at CERN in the neutron energy range from 10 to 300 keV relative to the 10B(n,a)7Li cross-section standard. Both reactions were ... -
Measurement and analysis of the 241-Am neutron capture cross section at the n_TOF facility at CERN
(AMER PHYSICAL SOC, 2018-05-24)
Article
Accés obertThe 241Am(n,¿ ) cross section has been measured at the n_TOF facility at CERN with the n_TOF BaF2 Total Absorption Calorimeter in the energy range between 0.2 eV and 10 keV. Our results are analyzed as resolved resonances ... -
The BRIKEN Project: extensive measurements of ß-delayed neutron emitters for the astrophysical r process
(2018-03)
Article
Accés obertAn ambitious program to measure decay properties, primarily ß-delayed neutron emission probabilities and half-lives, for a significant number of nuclei near or on the path of the rapid neutron capture process, has been ... -
Preparation and characterization of 33-S samples for 33-S(n,alpha)30-Si cross-section measurements at the n_TOF facility at CERN
(2018-05-11)
Article
Accés obertThin 33S samples for the study of the 33S(n,a)30Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of 33S powder onto a dedicated substrate made of kapton covered with thin layers of copper, ... -
Radiative neutron capture on 242Pu in the resonance region at the CERN n_TOF-EAR1 facility
(AMER PHYSICAL SOC, 2018-02-06)
Article
Accés obertThe spent fuel of current nuclear reactors contains fissile plutonium isotopes that can be combined with uranium to make mixed oxide (MOX) fuel. In this way the Pu from spent fuel is used in a new reactor cycle, contributing ... -
Experimental setup and procedure for the measurement of the 7Be(n,p)7Li reaction at n_TOF
(2018-04-11)
Article
Accés obertFollowing the completion of the second neutron beam line and the related experimental area (EAR2) at the n_TOF spallation neutron source at CERN, several experiments were planned and performed. The high instantaneous neutron ... -
Measurement of the U-238(n,gamma) cross section up to 80 keV with the total absorption calorimeter at the CERN n_TOF facility
(AMER PHYSICAL SOC, 2017-12)
Article
Accés obertThe radiative capture cross section of a highly pure (99.999%), 6.125(2) grams and 9.56(5)E-4 atoms/barn areal density 238U sample has been measured with the Total Absorption Calorimeter (TAC) in the 185 m flight path at ...
