Scattering of 15 C on 208 Pb at energies near the Coulomb barrier: Study of the experimental device response via the 12 C+ 208 Pb scattering

There are evidences that the 15 C nucleus has an extended neutron distribution or a "neutron halo", but this situation is far from clear. If 15 C has 1n-halo, the scattering dynamics should be affected and the angular distribution of the elastic channels should be sensitive to coupling eff...

Summary:There are evidences that the 15 C nucleus has an extended neutron distribution or a "neutron halo", but this situation is far from clear. If 15 C has 1n-halo, the scattering dynamics should be affected and the angular distribution of the elastic channels should be sensitive to coupling effects due to the halo configuration. The objetive of this study is to understand the role of the halo in 15 C by investigating its dynamical response in intense electric fields at energies close to the Coulomb barrier. For this purpose experiment IS619 was conducted performing the 15 C + 208 Pb elastic scattering reaction at HIE-ISOLDE, CERN. The beam energy was 4.37 MeV / u , which is very close to the Coulomb barrier of the system. The experimental setup used was the global detection system GLORIA, a six silicon telescopes array enable to measure the energy and angular distributions of the scattered particles. During the experiment, the 12 C+ 208 Pb scattering at 4.37 MeV / u was measured for calibration. The results of the 12 C+ 208 Pb measurement were used to fine-tune the geometry of the experimental setup and it is presented in this contribution.
