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 ...

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 ...

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 ...

Slow logarithmic relaxation in models with hierarchically constrained dynamics
(American Physical Society, 2001)
A general kind of model with hierarchically constrained dynamics is shown to exhibit logarithmic anomalous relaxation similar to a variety of complex strongly interacting materials. The logarithmic behavior describes most ...

Population of mixed-symmetry states via α transfer reactions
(The American Physical Society, 2008)
Within the neutron-proton interacting boson model we study the population of mixed-symmetry states via α transfer processes. Closed expressions are deduced in the case of the limiting Uπ+ν(5) and SUπ+ν(3). We find that the ...

Electromagnetic transitions and structure in the Z = N nucleus 46 V
(American Physical Society, 2001-10-01)
The nucleus 46V has been studied in the reaction 24Mg(28Si,apn) 46V at 115 MeV beam energy, using both Au and Pb backed targets. Lifetimes were obtained for 14 levels with DSAM analysis. Experimental B (E2) reduced transition ...
