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. ...

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, ...

Neutron capture cross sections for the Re/Os clock
(AIP Publishing, 2005)
The radioactive decay of 187Re → 187Os (t 1/2 = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the 187Os abundance is the difference between the natural abundance ...

Experimental determination of the 6,7Li nucleon densities
(American Institute of Physics, 2009)
In this work we present optical model analysis of new near barrier‐quasi‐elastic experimental data, for the systems 6,7Li+120Sn. From the analysis it was possible to extract the ground state nucleon densities of the weakly ...

Near-barrier scattering of 6 He and 11 Be
(American Institute of Physics, 2008)
Experiments on halo nuclei at energies around the Coulomb barrier can provide good quality data on elastic, inelastic, breakup and nucleon transfer reactions. This information turns out to be very important to understand ...

Fluctuations of a piston on top of a fluidized granular gas
(American Institute of Physics, 2009)
A fluidized granular gas in presence of a gravitational field is considered. It is enclosed in a box with a movable piston on the top. Molecular dynamics simulation results show that, if the box is not too wide, the system ...

Neutron capture cross section measurements at n_TOF of Np-237, Pu-240 and Am-243 for the transmutation of nuclear waste
(AIP Publishing, 2006)
Accurate and reliable neutron capture cross section data for actinides are necessary for the proper design, safety regulation and precise performance assessment of transmutation devices such as Fast Critical Reactors or ...

Decoherence as a Signature of an Excited State Quantum Phase Transition in Two Level Boson Systems
(American Institute of Physics, 2009)
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presence of quantum phase ...

Measurement of La-139(n,gamma) cross section at n_TOF
(American Institute of Physics, 2006)
The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance ...

Forced synchronization of a quantum dissipative dynamics
(American Institute of Physics, 2007)
We generalize the phenomenon of forced stochastic synchronization into the quantum domain within the framework of a paradigmatic spin-boson model (tunneling charge, or flipping spin 1/2 coupled to an environment) which ...
