The 33S(n,α)30Si cross section measurement at n-TOF-EAR2 (CERN): From 0.01 eV to the resonance region
(EDP Sciences, 2017)
The 33S(n,α)30Si cross section measurement, using 10B(n,α) as reference, at the n TOF Experimental Area 2 (EAR2) facility at CERN is presented. Data from 0.01 eV to 100 keV are provided and, for the first time, the cross ...

Monte carlo simulations of the n-TOF lead spallation target with the Geant4 toolkit: A benchmark study
(EDP Sciences, 2017)
Monte Carlo (MC) simulations are an essential tool to determine fundamental features of a neutron beam, such as the neutron flux or the γ-ray background, that sometimes can not be measured or at least not in every position ...

Measurement of the neutron capture cross section of the s -only isotope 204 Pb from 1 eV to 440 keV
(American Physical Society, 2007)
The neutron capture cross section of 204Pb has been measured at the CERN n TOF installation with high resolution in the energy range from 1 eV to 440 keV. An R-matrix analysis of the resolved resonance region, between 1 ...

Neutron capture cross section of unstable 63Ni: implications for stellar nucleosynthesis
(American Physical Society, 2013-01-08)
The 63Ni(n,γ) cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were ...

Time-of-flight and activation experiments on 147Pm and 171Tm for astrophysics
(EDP Sciences, 2017)
The neutron capture cross section of several key unstable isotopes acting as branching points in the s-process are crucial for stellar nucleosynthesis studies, but they are very challenging to measure due to the difficult ...

Dispersive spherical optical model of neutron scattering from 27 Al up to 250 MeV
(American Physical Society, 2002-03-01)
A spherical optical model potential (OMP) containing a dispersive term is used to fit the available experimental database of s(u) and sT for n127Al covering the energy range 0.1–250 MeV using relativistickinematics ...

Level densities of transitional Sm nuclei
(American Physical Society, 2005-06-01)
Experimentally determined level densities of the transitional isotopes 148, 149, 150, 152Sm at excitation energies below and around the neutron binding energy are compared with microcanonical calculations based on a Monte ...

Analytical expressions for the dispersive contributions to the nucleon-nucleus optical potential
(American Physical Society, 2003-06-01)
Analytical solutions of dispersion relations in the nucleon-nucleus optical model have been found for both volume and surface potentials. For the energy dependence a standard Brown-Rho function has been assumed for both ...

Is a global coupled-channel dispersive optical model potential for actinides feasible?
(American Physical Society, 2005-12-01)
An isospin-dependent coupled-channel optical model potential containing a dispersive term with a nonlocal contribution is used to simultaneously fit the available experimental database (including strength functions and ...
