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 ...

Measurement of resolved resonances of 232Th(n, γ) at the n_TOF facility at CERN
(American Physical Society, 2012)
The yield of the neutron capture reaction 232Th(n,γ) has been measured at the neutron time-of-flight facility n-TOF at CERN in the energy range from 1 eV to 1 MeV. The reduction of the acquired data to the capture yield ...

74 Ge(n, γ) cross section below 70 keV measured at n_TOF CERN
(Springer Nature, 2022)
Neutron capture reaction cross sections on 74Ge are of importance to determine 74Ge production during the astrophysical slow neutron capture process. We present new resonance data on 74Ge(n, γ) reactions below 70 keV neutron ...

Measurements of neutron cross sections for advanced nuclear energy systems at n_TOF (CERN)
(EDP Sciences, 2014)
The n_TOF facility operates at CERN with the aim of addressing the request of high accuracy nuclear data for advanced nuclear energy systems as well as for nuclear astrophysics. Thanks to the features of the neutron beam, ...

High accuracy, high resolution 235U(n,f) cross section from n_TOF (CERN) from 18 meV to 10 keV
(Springer Nature, 2022)
The 235U(n,f) cross section was measured in a wide energy range (18 meV–170 keV) at the n_TOF facility at CERN, relative to 6Li(n,t) and 10B(n,α) standard reactions, with high resolution and accuracy, with a setup based ...

Neutron-induced fission cross section of 234 U measured at the CERN n_TOF facility
(American Physical Society, 2014)
The neutron-induced fission cross section of 234U has been measured at the CERN n-TOF facility relative to the standard fission cross section of 235U from 20 keV to 1.4 MeV and of 238U from 1.4 to 200 MeV. A fast ionization ...

Predicting the optical observables for nucleon scattering on even-even actinides
(Chinese Physical Society, 2017)
The previously derived Lane consistent dispersive coupled-channel optical model for nucleon scattering on 232Th and 238U nuclei is extended to describe scattering on even-even actinides with Z=90-98. A soft-rotator-model ...

A general numerical solution of dispersion relations for the nuclear optical model
(IOP Publishing, 2001-07-16)
A general numerical solution of the dispersion integral relation between the real and the imaginary parts of the nuclear optical potential is presented. Fast convergence is achieved by means of the Gauss-Legendre integration ...

Hadronic Physics in Geant4: improvements and status for LHC Start
(2008)
An overview of recent developments in Geant4 hadronic modelling is provided with a focus on the start of the LHC experiments. Improvements in low-energy and high energy models were introduced. Many of these developments ...

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 ...
