Abstract: The neutron-rich isotopes 65,67Fe and 65Co have been produced at the LISOLfacility, Louvain-La-Neuve, in the proton-induced fission of 238U. Beams ofthese isotopes have been extracted with high selectivity by means of resonantlaser ionization combined with mass separation. Yrast and near-yrast levels of65Co have also been populated in the 64Ni+238U reaction at Argonne NationalLaboratory. The level structure of 65Co could be investigated by combining allthe information from both the 65Fe and 65Co beta decay and the deep-inelasticreaction. The 65Fe, 65Co and 67Fe decay schemes and the 65Co yrast structureare fully established. The 65,67Co level structures can be interpreted asresulting from the coexistence of core-coupled states with levels based on alow-energy proton-intruder configuration.
