Research Activities

Nuclear structure and Ion-Solid Interactions

The electromagnetic properties of low-lying nuclear states are very sensitive indicators of underlying nuclear structures, and in particular, of the interplay between single particle and collective excitations, which have been found to coexist even at low energies. We carry out experiments designed to measure magnetic dipole and electric quadrupole moments of very short- lived, nuclear states. We are currently developing new techniques to measure magnetic moments of nuclei far-from-stability. Radioactive beam facilities are being planned in the US and the world which will produce abundant quantities of nuclei that are likely to display "new physics" highlighted by very different p-n interactions, different spin-orbit couplings and coexistence of rather exotic shapes.

These experiments rely on the hyperfine interactions between the nuclei and the solid environment in which they are embedded. Thus, besides providing direct nuclear structure data, these experiments lead to detailed information on the fundamental interactions between ions and magnetic and non-magnetic solids. Experiments are performed with stable beams at the Tandem Accelerator at Yale University, and with both radioactive and stable beams at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory and at the 88" Cyclotron of the Lawrence Berkeley National Laboratory. These experiments utilize state-of-the-art detectors such as the Clover Ge detectors, solar cell arrays and the CLARION-HYBALL array.
