Coulomb excitation and transfer reactions with rare neutron-rich isotopes

Neutron-rich radioactive ion beams available from the HRIBF allow a variety of measurements around the (132)Sn region, including Coulomb excitation, fusion-evaporation, and neutron transfer. The B(E2; 0(+) -> 2(+)) value for first 2(+) excited states of even-even neutron-rich (132-136)Te and (126-134) Sn have been measured by Coulomb excitation in inverse kinematics. The results are discussed in terms of the shell model and the quasiparticle random phase approximation. Neutron transfer onto a (134)Te beam, from (9)Be and (13)C targets to populate single-particle states in (135)Te, has also been studied. Gamma rays from the (13)C((134) Te, (12)C) reaction were used to identify the vi(13/2) state in (135)Te, at an energy of 2109 keV. These and other results, and plans for future experiments with these neutron-rich beams, are presented.
