Abstract
The nuclides and have been produced by spallation reactions on vanadium targets at MeV. The subsequent decays to and have been studied via delayed -ray singles and coincidence techniques. In , excitation energies and -branching fractions have been determined for 19 levels. The values imply for the ground state of . For , evidence is found for four new branches and is assigned to the levels at 2326 and 2574 keV on the basis of the decay selection rules. The proposed decay scheme accounts for transitions between 10 levels, the first excited state being located at 182.6 keV. The structure of these nuclei is discussed in the weak coupling scheme.
