Neutron-Rich Nuclei at the Heavy Frontier

Wednesday, February 27, 4:10 PM - Nuclear Science Seminar
NSCL Lecture Hall

The focus of this talk will be on high-spin spectroscopy of neutron-rich nuclei with 94<Z<98, accessed via inelastic and transfer reactions, using heavy stable beams on radioactive targets. These complement spectroscopic investigations of elements with 100<Z<104 using fusion-evaporation reactions. The physics of the highest neutron orbitals at and beyond N=150 will be discussed. Valence orbitals here can originate from above the spherical shell gaps that are believed to be responsible for the stability of super-heavy elements. Thus, a precise mapping of single particle states in this deformed region can provide guidance and constraints for theories that attempt to predict the next higher spherical magic numbers.
