The Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory has recently produced the world's first post-accelerated beams of heavy neutron-rich nuclei. The first experiments with these beam are described, and the results discussed. values for neutron-rich 126,128Sn and 132,134,136Te isotopes have been measured by Coulomb excitation in inverse kinematics. The results for 132Te and 134Te ( N=80,82) show excellent agreement with systematics of lighter Te isotopes, but the B(E2) value for 136Te ( N=84) is unexpectedly small. Single-neutron transfer reactions with a 134Te beam on Be and 13C targets at energies just above the Coulomb barrier have also been studied.
