α-particle production in the scattering of 6He by Pb-208 at energies around the Coulomb barrier

New experimental data from the scattering of 6He + Pb-208 at energies around and below the Coulomb barrier are presented. The yield of breakup products coming from projectile fragmentation is dominated by a strong group of a particles. The energy and angular distribution of this group have been anal...

Descripción
Sumario:New experimental data from the scattering of 6He + Pb-208 at energies around and below the Coulomb barrier are presented. The yield of breakup products coming from projectile fragmentation is dominated by a strong group of a particles. The energy and angular distribution of this group have been analyzed and compared with theoretical calculations. This analysis indicates that the a particles emitted at backward angles in this reaction are mainly due to two-neutron transfer to weakly bound states of the final nucleus.
