8. Probing the 17F+p optical potential at near barrier energies in a microscopic approach

Poster

Data of a recently measured proton elastic scattering angular distribution of 17F+p, at 4.3 MeV/u, were analyzed in a double folding microscopic approach and the optical potential as well as the structure of this proton rich nucleus was probed. The data were collected over a wide angular range by means of the DINEX Si-detector array with an overall solid angle of ~0.8 sr. The 17F radioactive...

Poster

The study of exotic nuclear structures, like halo nuclei, is usually performed through indirect techniques, such as reactions. Unfortunately, the complexity of the reaction mechanism and the uncertainty in the choice of projectile-target interactions can cause ambiguities in the analysis of measurements. We present here a new way to extract information about the structure of halo nuclei...

27. Investigating the single-particle structure in 26Na via one neutron transfer in inverse kinematics using the new SHARC array

Poster

For neutron rich nuclei far from stability, it is known that the magic number N=20 disappears. Recent experiments, such as 24Ne(d,p) with TIARA [1] showed the breakdown of the N=20 magic number in favour of the new N=16 magic number. Theoretical work by Otsuka, Utsuno et al[2] has highlighted the importance of sodium isotope structure in quantifying the evolution of single particle energies...

36. Describing core excitation in the scattering of halo nuclei using a Transformed Harmonic Oscillator basis

Mr José Antonio Lay (Universidad de Sevilla)

Poster

It is well known that, an accurate description of reactions involving weakly-bound nuclei, such as halo nuclei, requires the inclusion of the coupling to the continuum (i.e., unbound) states. For two-body projectiles, a successful technique to describe these processes is the Continuum-Discretized Coupled-Channels (CDCC) method. Here the continuum is replaced by a discrete set of functions,...

42. Three-body breakup of 11Li with the eikonal method

E. C. Pinilla (Universite Libre de Bruxelles)

Poster

We use a four-body eikonal model to analyze the experimental breakup cross section of 11Li on 208Pb at 70 MeV/A [1]. It is a current debate if the large concentration of dipole strength at low energies is due to the 11Li low binding energy or if it is due to a resonance effect. First we compute 9Li+n+n three-body phase shifts for J=0+,1- and 2+. A relatively narrow structure is found in the...

72. Elastic scattering of the halo nucleus 11Li and its core 9Li on 208Pb at energies around the Coulomb barrier

Mr Mario Cubero (Instituto Estructura de la Materia, CSIC, Spain)

Poster

The discovery of the halo nuclei has brought renewed interest in the modeling of nuclear reactions. This structure will affect the reaction properties at near Coulomb barrier energies. Therefore we have studied, for the first time, the dynamics of the halo nucleus 11Li in presence of a strong electric field of 208Pb at energies below, 24.2 MeV, and around, 29.7 MeV, the Coulomb barrier at...
