Abstract
The low-energy levels of were populated by decay of , which was produced via projectile fragmentation of a beam at . Delayed -gated rays with energies of 438 and were observed in coincidence with fragments and assigned to the and transitions, respectively, in . Isomeric -ray transitions are also reported for and . The low-energy structure of shows remarkable similarity to those of the isotopic and isotonic suggesting that these nuclides share the same and closed shell structures with neutron-rich .
