Multiband coupling and nuclear softness in optical model calculations for even-even and odd-A actinides
(EDP Sciences, 2020)
A new dispersive multiband coupled channels optical model with soft-rotator “effective” deformations is proposed to describe nucleon scattering on even-even and odd-A actinides. The impact of the introduction of axial and ...

Neutron-induced fission cross section of 245 Cm: New results from data taken at the time-of-flight facility n_TOF
(American Physical Society, 2012)
The neutron-induced fission cross section of 245Cm 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 236U(n,f) cross section from 170 meV to 2 MeV at the CERN n_TOF facility
(American Physical Society, 2011)
The neutron-induced fission cross section of 236U was measured at the neutron Time-of-Flight (n-TOF) facility at CERN relative to the standard 235U(n,f) cross section for neutron energies ranging from above thermal to ...

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 ...

Optical model with multiple band couplings using soft rotator structure
(EDP Sciences, 2017)
A new dispersive coupled-channel optical model (DCCOM) is derived that describes nucleon scattering on 238U and 232Th targets using a soft-rotator-model (SRM) description of the collective levels of the target nucleus. SRM ...

The 93Zr(n, γ) reaction up to 8 keV neutron energy
(American Physical Society, 2013)
The (n,γ) reaction of the radioactive isotope 93Zr has been measured at the n-TOF high-resolution time-of-flight facility at CERN. Resonance parameters have been extracted in the neutron energy range up to 8 keV, yielding ...

Neutron-induced fission cross section of 234U and 237Np measured at the CERN Neutron Time-of-Flight (n_TOF) facility
(The American Physical Society, 2010)
A high-resolution measurement of the neutron-induced fission cross section of 234U and 237Np has been performed at the CERN Neutron Time-of-Flight facility. The cross sections have been determined in a wide energy range ...

Angular distributions of protons scattered by 40 Ar nuclei with excitation of the 2 + (1.46 MeV) and 3 − (3.68 MeV) collective levels for incident energies of 25.1, 32.5, and 40.7 MeV
(The American Physical Society, 2007)
Elastic and inelastic scattering of unpolarized and polarized protons by 40Ar nuclei for incident energies between 20 and 50 MeV has been studied by reanalyzing experimental scattering spectra for the 2+(1.46 MeV) and ...

High-accuracy U233 (n,f) cross-section measurement at the white-neutron source n_TOF from near-thermal to 1 MeV neutron energy
(The American Physical Society, 2009)
The 233U(n,f) cross section has been measured at the white neutron source n-TOF in a wide energy range with a dedicated fission ionization chamber. We report here the results from ∼30 meV to 1 MeV neutron energy. The ...
