β decay of67Co

Abstract
The β-decay properties of 67Co produced in proton-induced fission of 238U were measured by the detection of β-delayed γ rays emitted from an isotopically pure mass-separated source obtained by laser ionization. The measured half-life of 0.425(20) s is more accurate than previous values. New γ transitions were observed, and corresponding branching ratios and logft values were deduced. The 67Co decay scheme is discussed in terms of the single-particle shell model.
