Level structure of and from decay spectroscopy, and reflection asymmetry in
Résumé
and were produced at the IGISOL facility through proton-induced fusion-evaporation reactions and have been studied using -particle spectroscopy, as well as and -electron coincidence spectroscopy. The level scheme of , daughter of , and of , daughter of were reconstructed. An interpretation of levels as and parity-doublet bands is proposed. Such bands appear in reflection-asymmetric models and would be an indication of a static reflection asymmetric shape for .
