Simultaneous analysis of elastic scattering and transfer/breakup channels for the 6 He + 208 Pb reaction at energies near the Coulomb barrier
The elastic and α-production channels for the 6He+208Pb reaction are investigated at energies around the Coulomb barrier (Elab=14, 16, 18, 22, and 27 MeV). The effect of the two-neutron transfer channels on the elastic scattering has been studied within the Coupled-Reaction-Channels (CRC) method. We...

| Sumario: | The elastic and α-production channels for the 6He+208Pb reaction are investigated at energies around the Coulomb barrier (Elab=14, 16, 18, 22, and 27 MeV). The effect of the two-neutron transfer channels on the elastic scattering has been studied within the Coupled-Reaction-Channels (CRC) method. We find that the explicit inclusion of these channels allows a simultaneous description of the elastic data and the inclusive α cross sections at backward angles. Three-body Continuum-Discretized Coupled-Channels (CDCC) calculations are found to reproduce the elastic data, but not the transfer/breakup data. The trivial local polarization potential (TLP) derived from the CRC and CDCC calculations are found to explain the features found in previous phenomenological optical model calculations for this system. |
