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 ...

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 ...

Nucleon scattering on actinides using a dispersive optical model with extended couplings
(American Physical Society, 2016)
The Tamura coupling model [Rev. Mod. Phys. 37, 679 (1965)] has been extended to consider the coupling of additional low-lying rotational bands to the ground-state band. Rotational bands are built on vibrational ...

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 ...

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 ...

Saturation of coupling of collective levels in optical model calculations of even-even actinides
(EDP Sciences, 2017)
Saturation of the coupling-scheme is studied in dispersive optical model calculations of nucleon induced reactions on 238U target. Recently derived potential that is based on a soft-rotator-model (SRM) description of the ...

A Lane consistent optical model potential for nucleon scattering on actinide nuclei with extended coupling
(EDP sciences, 2016)
An extension for odd-A actinides of a previously derived dispersive coupledchannel optical model potential (OMP) for 238U and 232Th nuclei is presented. It is used to fit simultaneously all the available experimental ...

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 ...

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 ...

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 ...
