Abstract: The nuclear structure of 67Co has been investigated through 67Fe β decay. The 67Fe isotopes were produced at the LISOL facility in proton-induced fission of 238U and selected using resonant laser ionization combined with mass separation. The application of a new correlation technique unambiguously revealed a 496(33) ms isomeric state in 67Co at an unexpected low energy of 492 keV. A 67Co level scheme was deduced. Proposed spin and parities suggest a spherical (7/2−) 67Co ground state and a deformed first excited (1/2−) state at 492 keV, interpreted as a proton 1p-2h prolate intruder state.
