Abstract
Low-spin, low energy-levels in have been studied following the -decay of a 17-s and a 4-s respectively. A number of new transitions and levels are established in with improved support for spin and parity assignments for previously known states. In addition, the presence of two pairs of levels separated by only 14 keV is confirmed. Four new levels are observed in three of them are below 1 MeV excitation energy. The structure of these nuclides is discussed, focusing on three-quasiparticle cluster structures, movement of the Fermi level, and extrapolations for the single-neutron levels in
