Abstract
High-spin structures in the neutron-rich nuclei and produced in the spontaneous fission of have been investigated by prompt -ray spectroscopy. A collective band structure in is identified. Several sidebands along with the new high-spin states in are also identified. Particle-plus-rotor model calculations indicate that the yrast bands in and most probably originate from coupling of the orbital to the ground states of and The ground state configurations of are and respectively.
