ata for scattering of 6He from 197Au, 208Pb, and 209Bi targets at low energies were consistently analyzed by use of the continuum-discretized coupled-channels method and the dineutron model of the projectile. A very good description of the experimental data was obtained with the strength of the dipole couplings reduced by 50%. We find that the...

Elastic cross sections for the scattering of ⁶He projectiles by ²⁰⁸Pb at energies around the Coulomb barrier measured at the Cyclotron Research Center of Louvain la Neuve (Belgium) have been analyzed using a simple analytic expression for the elastic cross section obtained in a semiclassical model. The results are consistent with recent Optical...

The structure of the three-body Borromean nucleus He6 is approximated by a two-body di-neutron cluster model. The binding energy of the 2n-α system is determined to obtain a correct description of the 2n-α coordinate, as given by a realistic three-body model calculation. The model is applied to describe the breakup effects in elastic scattering...

Differential cross sections and T20 and 20TT analyzing powers have been measured for 70 MeV Li7 breakup into the particle plus triton channel, on a Sn120 target. Measurements were made for both continuum breakup and sequential breakup via the 4.63 MeV state in Li7. The T20 data for the continuum breakup do not agree with a semiclassical Coulomb...

The T20 analyzing powers have been measured for the 120Sns7Li, 8Be!2ad119In and 120Sns7Li, 6Li*!a+dd121Sn transfer breakup reactions, using a 70 MeV beam. The data exhibit excellent agreement with the results of coupled reaction channels calculations, providing an important test of these calculations when applied to the transfer breakup...

The structure and dynamics of 8He have been studied through the collision process with a 208 Pb target at energies of 22 and 16 MeV, above and below the Coulomb barrier, respectively. The energy and angular distributions of the elastically scattered 8He and the 6,4He fragments were measured. In this paper, we discuss the method used to...

The dynamics of 8He around the Coulomb barrier is investigated by measuring the energy and angular distribution of the elastic 8He and the 6He and 4He fragment yields in the collision process with a 208Pb target. The experiment was carried out at SPIRAL/GANIL in October 2010. The experimental results will provide information about the relevant...

We have measured the angular distributions of elastic scattering and 6,4He fragments produced in the collisions of an exotic beam of 8He on a 208Pb target at laboratory energies of 18 and 22 MeV, just around the Coulomb barrier (19 MeV). The measurements were performed at the SPIRAL/GANIL facility in Caen, France. In this paper, we present...

The skin nucleus 8He is investigated by measuring the angular distribution of the elasticly scattered 8He and the 6,4He fragments produced in the collision with a 208Pb target at 22 MeV, just above the Coulomb barrier. The experiment was carried out at SPIRAL/GANIL in 2010. Here we present preliminary results for the elastic scattering.

Dramatic differences in the elastic scattering of the neutron rich nuclei 6He and 8He are found when new high quality data for the 8He+208Pb system are compared with previously published 6He+208Pb data at the same laboratory frame incident energy. The new 8He data are of the same level of detail as for stable beams. When comparing them with...

Preliminary results on the 11Be+120Sn quasielastic scattering as well as the 11Be → 10Be + n breakup channel are presented in this work. The angular distributions of these channels were measured at REX-ISOLDE-CERN.
