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.
