Description :
The present work aims to extend the experiment reported in refs. [1] and [2] concerning the Ne-18(alpha, p)Na-21 reaction, by making a measurement at a lower energy (1.50-3.00 MeV in the centre-of-mass frame of the Ne-18 + alpha system) in an attempt to observe other states in the level structure of...

1st Euroconference on Vortex Matter in Superconductors at Extreme Scales and Conditions
Description :
Beyond the well-known Abrikosov and giant vortex configurations, we describe new types of solutions to the Landau-Ginzburg (LG) equations for low temperature superconductivity. These solutions correspond to ring-like current vortices surrounding one another in concentric patterns, which in addition ...

A two-compartment model for understanding the simulated three-dimensional circulation in Prince William Sound, Alaska
Description :
A two-compartment model of Prince William Sound (PWS), Alaska, is developed, One compartment, corresponding to the southern PWS, represents advective phenomena, while the other is dominated by diffusion, This simple model is shown to reproduce rather well the temporal evolution of the mass of a pass...

3rd International Conference on Modelling of Global Climate Change and Variability
Description :
To understand the influence of the Bering Strait on the World Ocean's circulation, a model sensitivity analysis is conducted. The numerical experiments are carried out with a global, coupled ice-ocean model. The water transport through the Bering Strait is parametrized according to the geostrophic c...

Infinite-dimensional SRB measures
Description :
We review the basic steps leading to the construction of a Sinai-Ruelle-Bowen (SRB) measure for an infinite lattice of weakly coupled expanding circle maps, and we show that this measure has exponential decay of space-time correlations. First, using the Perron-Frobenius operator, one connects the dy...

4th International Conference on Radioactive Nuclear Beams
Description :
The Ne-19(p,gamma)Na-20 as well as the Ne-19(d,n)Na-20 reaction have been studied in inverse kinematics using Ne-19 radioactive beams. Upper and lower limits for the Ne-19(p,gamma)Na-20 astrophysical reaction rate have been deduced, for the first time on the basis of direct experimental data. It is ...

5th International Conference on Nucleus-Nucleus Collisions
Description :
Nucleus-nucleus reaction mechanisms at incident energies below 10 MeV/u are governed by mean field effects. Nucleon-nucleon collisions begin to become important as the energy increases above the Fermi energy. This evolution manifests itself experimentally in the modification of the directed flow of ...

Description :
The N-13 + C-12,C-13 elastic scatterings have been measured at laboratory energies of 16.3, 20. and 29.5 MeV. It is shown that the N-13 + C-12 and C-13 + C-12 systems seem to comply with charge symmetry. A preliminary analysis of the N-13 + C-13 system reveals very interesting data which cannot be r...

International Symposium on Physics of Unstable Nuclei
Description :
The ARENAS(3) facility, coupling the two cyclotrons of Louvain-la-Neuve, is intensively been used over the past years for cross-section measurements of nuclear reactions of astrophysical interest. We will describe the characteristics of the available beams and the experiments going on using these be...
