Abstract
The level structure of odd-odd has been studied at CERN/ISOLDE following the decay of and the β-delayed neutron decay of . Elemental and isobaric separation were accomplished by use of a resonance ionization laser ion source and an on-line mass separator, respectively. Both γ-ray singles and coincidence data were taken as a function of time. New levels at 279, 441, 555, 617, and 1385 keV have been identified and given proposed spin and parity assignments of , , , , and , respectively, following β-delayed neutron decay of . New levels have been identified at 1900, 2170, and 2430 keV following the decay of . The resulting level structures are compared to shell-model calculations using the CD Bonn interaction and scaled and unscaled Kuo-Herling interactions developed for the region. Remarkably enough, the unscaled Kuo-Herling interaction provides the best fit for the levels below 1 MeV.
