Many changes have been observed in nuclei as we move away from the valley of stability and it is important both to nuclear structure physics and to understanding the synthesis of nuclei in the cosmos, to study how these changes affect single-particle states, especially around doubly-magic nuclei. Single-neutron transfer reactions, such as the (d,p) reaction, are sensitive probes of low angular momentum single-particle states. When employed in inverse kinematics, using Radioactive Ion Beams (RIBs), the single-particle nature of exotic nuclei can be explored.
A number of one-neutron transfer reaction studies in inverse kinematics have been performed at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL). Our studies have been focused on the medium-mass neutron-rich region of the Segre Chart, close to the expected r-process path, and to the Z=50 and N=50 and N=82 shell closures.
I will present results from measurements with beams close to doubly-magic 132Sn to study the single-particle structure of 131Sn, 133Sn, and 135Te. I will also show the first results from a recent experiment to study the halo states and resonances in 11Be using the 10Be(d,p) reaction in inverse kinematics.
