The 64Co beta-decay feeding levels in the well-studied 64Ni nucleus were investigated. Whereas the previously known 64Co decay scheme merely contained 2 gamma rays, the decay scheme established in this work contains 18, of which 5 are observed in this work and 6 were previously observed in an (n,gamma) study but not placed in the 64Ni level scheme. Surprisingly, one additional level—placed at an excitation energy of 3578.7 keV—could be determined. The observed beta-decay paths involve allowed nf5/2→pf7/2 and np1/2→pp3/2 transitions. Three strongly fed levels around 4 MeV are interpreted to possess possible proton-intruder character.
