Angular correlation measurements were made on 12 direct cascades and 5 skip cascades in /sup 140/Ba. Levels in /sup 140/Ba were populated from the 64-sec ..beta.. decay of /sup 140/Cs, which was populated from the decay of /sup 140/Xe. The fission-product /sup 140/Xe activity was produced by the TRISTAN isotope separator system. The most intense transitions were measured in coincidence with the first-excited state-to-ground-state transition in even-even /sup 140/Ba. Definite spin assignments were made for eight levels and tentative spin assignments for five levels. Values are given for the angular correlation coefficients, and multipolarity mixing ratios are listed where applicable. Systematics for N=84 isotones are discussed in light of assignments made for /sup 140/Ba. (AIP)
