Shape phase transitions in odd-A nuclei
(American Institute of Physics, 2008)
We investigate shape phase transitions in odd nuclei within the Interacting Boson Fermion Model. Special attention is given to the case of the transition from the vibrational behaviour to the stable axial deformation. ...

Energy fluctuations in a randomly driven granular fluid
(Taylor & Francis, 2009)
We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is derived and the hydrodynamic eigenvalues are ...

Critical-point symmetries in Boson-Fermion systems: The case of shape transitions in odd nuclei in a multiorbit model
(American Physical Review, 2007-02-05)
We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model [E(5/12)] to describe odd nuclei at the critical point in the transition from the spherical to γ-unstable behavior. In ...

Aspectos estructurales y cinemáticos del disco galáctico joven
(2006)
En este trabajo nos proponemos reanalizar la distribución espacial y las propiedades cinemáticas de la componente estelar masiva del Cinturón de Gould a partir de una clasificación más rigurosa y precisa de sus miembros. ...

Overview of Neutrino–Nucleus Interactions
(Jagiellonian University, 2009)
Neutrino–nucleus reactions are surveyed. The approximations usually made are identified and a comparison to the corresponding electron–nucleus processes is presented. Impulse Approximation (IA), factorization of ...

Global fluctuations in dissipative systems
(American Institute of Physics, 2009)
Our goal here is to investigate the influence of velocity correlations on the fluctuations of several global quantities for two different systems. In the first case, we study the fluctuations of the total number of particles, ...

Dynamics of annihilation. II. Fluctuations of global quantities
(American Physical Society, 2008)
We develop a theory for fluctuations and correlations in a gas evolving under ballistic annihilation dynamics. Starting from the hierarchy of equations governing the evolution of microscopic densities in phase space, ...

UBF(5) to SUBF(3) shape phase transition in odd nuclei for j=1/2, 3/2, and 5/2 orbits: The role of the odd particle at the critical point
(The American Physical Society, 2009)
We investigate the phase transition in odd nuclei within the Interacting Boson Fermion Model in correspondence with the transition from spherical to stable axially deformed shape. The odd particle is assumed to be moving ...

Resonance capture cross section of 207 Pb
(American Physical Society, 2006-11-16)
The radiative neutron capture cross section of 207 Pb has been measured at the CERN neutron time of flight installation n TOF using the pulse height weighting technique in the resolved energy region. The measurement has ...
