AB The neutron-rich carbon isotope 15C was postulated to be a halo nucleus(Sn = 1215 keV, S2n = 9395 keV) according to different high-energyexperiments. If so, it would be the only halo nucleus exhibiting a “pure”s-wave structure of the ground state. At low collision energies, the effectof this halo structure should manifest as a strong absorption pattern inthe angular distribution of the elastic cross section, with a total suppressionof the nuclear rainbow due to the large neutron transfer and breakupprobabilities, enhanced by the halo configuration. The IS619 experiment,carried out at the HIE-ISOLDE facility at CERN (Switzerland), is the firstdynamical study of this nucleus at energies around the Coulomb barrier. Itaims to probe the halo structure via the measurement of the elastic crosssection on a high-Z 208Pb target. Preliminary results of the elastic crosssection are discussed and compared to Optical Model calculations.
