Description of nucleon scattering on 208Pb by a fully Lane-consistent dispersive spherical optical model potential
(EDP Sciences, 2017)
A fully Lane-consistent dispersive spherical optical potential is proposed to describe nucleon scattering interaction with doubly magic nucleus 208Pb up to 200 MeV. The experimental neutron total cross sections, elastically ...

Astrophysics at n-TOF facility
(American Institute of Physics, 2010)
Heavy elements with Z ≥ 30 are made by neutron capture reactions during stellar He burning and presumably in supernovae. This contribution deals mainly with the slow neutron capture (s) process which is responsible for ...

Neutron capture on 94Zr: Resonance parameters and Maxwellian-averaged cross sections
(American Physical Society, 2011)
The neutron capture cross sections of the Zr isotopes play an important role in nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier isotopes passes through the neutron magic nucleus ...

Neutron physics of the Re/Os clock. III. Resonance analyses and stellar (n, γ) cross sections of 186, 187, 188Os
(The American Physical Society, 2010)
Neutron resonance analyses have been performed for the capture cross sections of 186Os, 187Os, and 188Os measured at the n-TOF facility at cern. Resonance parameters have been extracted up to 5, 3, and 8 keV, respectively, ...

Dispersive optical model description of nucleon scattering on Pb and Bi isotopes
(American Physical Society, 2020)
A recently derived dispersive optical model potential (DOMP) for 208Pb is extended to consider the nonlocality in the real potential and the shell gap in the definition of the nuclear imaginary potentials near the Fermi ...

Dispersive coupled-channels optical-model potential with soft-rotator couplings for Cr, Fe, and Ni isotopes
(American Physical Society, 2013)
An approximate Lane-consistent dispersive coupled-channels optical potential is derived that describes nucleon-induced reactions on even iron isotopes. Realistic saturated couplings for 54,56,58Fe nuclei are built using ...

The 92Zr(n,γ) reaction and its implications for stellar nucleosynthesis
(The American Physical Society, 2010)
Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear ...

Dispersive coupled-channel analysis of nucleon scattering from 232 Th up to 200 MeV
(American Physical Society, 2005-08-01)
An isospin-dependent coupled-channels optical model potential containing a dispersive term (including nonlocal contribution) is used to simultaneously fit the available experimental database (including strength functions ...

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 ...

Approximate Lane consistency of the dispersive coupled-channels potential for actinides
(The American Physical Society, 2007)
A previously derived dispersive coupled-channels optical model potential for nucleon scattering on 232Th and 238U nuclei [Capote, Soukhovitskii, Quesade, and Chiba, Phys. Rev. C 72, 064610 (2005)] has been tested against ...
