Hydrodynamic profiles for an impurity in an open vibrated granular gas
(American Physical Society, 2006)
The hydrodynamic state of an impurity immersed in a low density granular gas is analyzed. Explicit expressions for the temperature and density fields of the impurity in terms of the hydrodynamic fields of the gas are ...

Flux reversal in a simple random-walk model on a fluctuating symmetric lattice
(American Physical Society, 2006)
A rather simple random-walk model on a one-dimensional lattice is put forward. The lattice as a whole switches randomly between two possible states which are spatially symmetric. Both lattice states are identical, but ...

Steady self-diffusion in classical gases
(IOP Publishing Ltd., 2013-08)
A steady self-diffusion process in a gas of hard spheres at equilibrium is analyzed. The system exhibits a constant gradient of labeled particles. Neither the concentration of these particles nor its gradient are assumed ...

Phase transitions in the interacting boson fermion model: The γ -unstable case
(American Physical Society, 2005-01-11)
The phase transition around the critical point in the evolution from spherical to deformed γ-unstable shapes is investigated in odd nuclei within the interacting boson fermion model. We consider the particular case of an ...

Shape phase transition in odd nuclei in a multi- j model: The UB(6) ⊗ UF(12) case
(The American Physical Society, 2007)
The phase transition in odd nuclei when the underlying even-even core nuclei experience a transition from spherical to deformed γ-unstable shapes is investigated. The odd particle is assumed to be moving in the three ...

Measurement of the U 238 (n,γ) cross section up to 80 keV with the total absorption calorimeter at the CERN n-TOF facility
(American Physical Society, 2017)
The radiative capture cross section of a highly pure (99.999%), 6.125(2) grams and 9.56(5)× 10−4 atoms/barn areal density 238U sample has been measured with the Total Absorption Calorimeter (TAC) in the 185 m flight path ...

Interplay between valence and core excitation mechanisms in the breakup of halo nuclei
(American Physical Review, 2012-12-05)
The phenomenon of core excitation in the breakup of a two-body halo nucleus is investigated. We show that this effect plays a significant role in the reaction dynamics and, furthermore, its interference with the valence ...

Relativistic Coulomb excitation of the giant dipole resonance in nuclei: How to calculate transition probabilities without invoking the Liénard-Wiechert relativistic scalar and vector potentials
(American Physical Society, 2006-03-17)
The conclusions extracted from a recent study of the excitation of giant dipole resonances in nuclei at relativistic bombarding energies open the way for a further simplification of the problem. It consists in the elimination ...

Relativistic descriptions of inclusive quasielastic electron scattering: Application to scaling and superscaling ideas
(The American Physical Society, 2009)
An analysis of inclusive quasielastic electron scattering is presented using different descriptions of the final-state interactions within the framework of the relativistic impulse approximation. The relativistic Green's ...

Core excitation effects in the breakup of the one-neutron halo nucleus 11Be on a proton target
(American Physical Society, 2012)
We investigate the phenomenon of core excitation in the inelastic and breakup of two-body halo nuclei, composed by a valence nucleon and a core. To evaluate the importance of this effect we propose a simple reaction model ...
