Simulación por ordenador de un modelo de cristal líquido dipolar
(1999-07-02)
En esta memoria abordamos el estudio, utilizando simulación en ordenador de la influencia de las interacciones dipolares en la formación y estabilización de fases de cristal líquido. Se ha utilizado el modelo de Gay-Berne, ...

New measurement of the 242Pu(n,γ) cross section at n_TOF
(EDP Sciences, 2016)
The use of MOX fuel (mixed-oxide fuel made of UO2 and PuO2) in nuclear reactors allows substituting a large fraction of the enriched Uranium by Plutonium reprocessed from spent fuel. With the use of such new fuel composition ...

Nonlinear driven diffusive systems with dissipation: Fluctuating hydrodynamics
(American Physical Society, 2012)
We consider a general class of nonlinear diffusive models with bulk dissipation and boundary driving and derive its hydrodynamic description in the large size limit. Both the average macroscopic behavior and the fluctuating ...

Experimental Study of the Pygmy Dipole Resonance in the 68Ni Nucleus
(Jagiellonian University, 2018)
It is known that the low-energy E1 strength, known as the Pygmy Dipole Resonance (PDR), can be excited by both isovector and isoscalar probes. In this work, we report on the results of an experiment, carried out at the ...

The nature of the gould belt from a fractal analysis of its stellar population
(IOP Publishing Ltd., 2007-09-20)
he Gould Belt (GB) is a system of gas and young, bright stars distributed along a plane that is inclined with respect to the main plane of the Milky Way. Observational evidence suggests that the GB is our closest star ...

Two-neutron transfer in the 6 He + 120 Sn reaction
(American Physical Society, 2018)
A large yield of α particles produced in the 120 Sn ( 6 He , α ) reaction was measured at 20.3-, 22.2-, 22.4-, and 24.5-MeV bombarding energies. The α particles are distributed over a broad energy range ...

Observation of two-proton radioactivity of Mg19 by tracking the decay products
(American Physical Society, 2007-10-29)
We have observed the two-proton radioactivity of the previously unknown 19Mg ground state by tracking the decay products in-flight. For the first time, the trajectories of the 2p-decay products, 17Ne+p+p, have been measured ...

Phase transitions, interfacial fluctuations and hidden symmetries for fluids near structured walls
(Indian Academy of Sciences, 2005)
Fluids adsorbed at micro-patterned and geometrically structured substrates can exhibit novel phase transitions and interfacial fluctuation effects distinct from those characteristic of wetting at planar, homogeneous walls. ...

Role of the continuum in reactions with weakly bound systems: A comparative study between the time evolution of a break-up wave function and its coupled-channel approximation
(The American Physical Society, 2009)
We exploit a model describing the breakup of weakly bound nuclei that can be used as a laboratory for testing different prescriptions that have been advanced in the literature to take into account the nearby presence of ...

Ionoluminescent response of several phosphor screens to keV ions of different masses
(AIP Publishing, 2008-09-15)
We have characterized the ionoluminescent response of several phosphor powder materials when irradiated with ions of different masses H+ ,He+ ,Ar+ accelerated to keV energies. In particular, we have determined the ...
