The neutron-halo nucleus 6He has been extensively studied using the TWINSOL apparatus at the Nuclear Structure Laboratory on the campus of the University of Notre Dame. During the past decade, the structure of the exotic nucleus 6He has been elucidated and the neutron-halo nature of this nucleus has been confirmed through direct and indirect methods. Detailed measurements of the four-neutron evaporation cross section following the fusion of 6He and 209Bi for center-of-mass energies of 23.5 and 30.7 MeV have been made. The fusion of 6He with a 209Bi target has been studied at energies near to and below the Coulomb barrier. A neutron-α-particle coincidence experiment has been performed to study the 6He-209Bi two-neutron transfer to unbound states of 211Bi. Experimental procedures and results of these experiments will be presented and discussed.
