Abstract
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.
