The beta-decay- properties of Co-67 produced in proton-induced fission of U
-238 were measured by the detection of beta-delayed gamma rays emitted from
an isotopically pure mass-separated source obtained by laser ionization. T
he measured half-life of 0.425(20) s is more accurate than previous values.
New gamma transitions were observed, and corresponding branching ratios an
d log ft values were: deduced. The Co-67 decay scheme is discussed in terms
of the single-particle shell model. [S0556-2813(99)04904-3].
