Nuclear transparencies in relativistic A(e, e′ p) models
(Elsevier, 2004)
Relativistic and unfactorized calculations for the nuclear transparency extracted from exclusive A(e,e′p) reactions for 0.3≤Q2≤10 (GeV/c)2 are presented for the target nuclei C, Si, Fe and Pb. For Q2≥0.6 (GeV/c)2, the ...

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 ...

Probing additional dimensions in the universe with neutron experiments
(Elsevier, 2004)
We carry out a simple analysis of (n+3)-dimensional gravity in the context of recent work on 'large' supplementary dimensions and deduce a formula for the expected compactification radius for the n additional dimensions ...

The sextic oscillator as a γ-independent potential
(American Physical Society, 2004-01-01)
The sextic oscillator is proposed as a two-parameter solvable g-independent potential in the Bohr Hamiltonian. It is shown that closed analytical expressions can be derived for the energies and wave functions of the first ...

Three-body continuum discretization in a basis of transformed harmonic oscillator states
(American Physical Society, 2005-01-01)
The inclusion of the continuum in the study of weakly bound three-body systems is discussed. A transformed harmonic oscillator basis is introduced to provide an appropriate discrete and finite basis for treating the ...

A semiclassical Analysis of the He-6+pb-208 Elastic Scattering.
(Jagellonian University, 2006)
Elastic cross sections for the scattering of ⁶He projectiles by ²⁰⁸Pb at energies around the Coulomb barrier measured at the Cyclotron Research Center of Louvain la Neuve (Belgium) have been analyzed using a simple analytic ...

Three-body continuum-discretized coupled-channel calculations for 6 He scattering from heavy nuclei
(American Physical Society, 2005-09-01)
ata for scattering of 6He from 197Au, 208Pb, and 209Bi targets at low energies were consistently analyzed by use of the continuum-discretized coupled-channels method and the dineutron model of the projectile. A very good ...

Superscaling analysis of inclusive electron scattering and its extension to charge-changing neutrino-nucleus cross sections beyond the relativistic Fermi gas approach
(American Physical Society, 2006-11-15)
Superscaling analyses of inclusive electron scattering from nuclei are extended from the quasielastic processesto the delta excitation region. The calculations of (e, e ) cross sections for the target nucleus 12 C at ...

U(5)-O(6) transition in the interacting boson model and the E(5) critical point symmetry
(American Physical Society, 2003-10-01)
The relation of the recently proposed E(5) critical point symmetry with the interacting boson model is investigated. The large-N limit of the interacting boson model at the critical point in the transition ...

Meson-exchange currents in (e,e'p) recoil polarization observables
(American Physical Society, 2003-09-01)
A study of the effects of meson-exchange currents and isobar configurations in A(e,e'p)B reactions is presented. We use a distorted wave impulse approximation model where final-state interactions ...
