Departmental Seminar

Shell structure beyond the neutron-rich doubly magic nucleus 132Sn

Professor Andrew Stuchbery
Head of Department
Department Nuclear Physics

Only recently has it become possible to study neutron-rich nuclei by the use of radioactive-beam accelerators. Nuclear shell structure and the magic numbers, once thought immutable, are now known to change for neutron-rich isotopes. This talk will focus on experimental results from the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory in which single-neutron states in 133Sn, analogous to electron excitations in alkali atoms, were identified and characterized. The excited states were populated by heavy-ion transfer reactions, and measurements include excitation energies, spin and parities, spectroscopic factors, and lifetimes.

All staff and students are welcome to attend.
