Study of the scattering of $^{15}$C at energies around the Coulomb barrier

The neutron rich carbon isotope $^{15}$C is the only known case of an almost "pure" 2s$_{1/2}$ single-neutron halo ground state configuration. At collision energies around the Coulomb barrier the reaction dynamics is expected to be dominated by single neutron transfer and breakup. To inves...

Sumario:The neutron rich carbon isotope $^{15}$C is the only known case of an almost "pure" 2s$_{1/2}$ single-neutron halo ground state configuration. At collision energies around the Coulomb barrier the reaction dynamics is expected to be dominated by single neutron transfer and breakup. To investigate these effects, we have measured the scattering of  $^{15}$C with a $^{208}$Pb target at 65 MeV at the HIE-ISOLDE facility in CERN (Geneva, Switzerland). The preliminary data demonstrates the presence of a strong long-range absorption pattern in the angular distribution of the elastic cross section. The results are discussed in the framework of Optical Model calculations
