Abstract

Level structures of neutron-rich Xe140 nucleus have been reinvestigated by using a triple γ coincidence study from the spontaneous fission of Cf252. Several new levels and transitions are identified. The previously observed s=+1 octupole band structure is confirmed and expanded. Another set of the ΔI=2 positive and negative parity bands connected by strong E1 transitions is proposed as the s=1 octupole band structure. Thus, the s=±1 doublet octupole bands are completed in Xe140. The experimental B(E1)/B(E2) branching ratios indicate that the octupole correlations in Xe140 are weak. The other characteristics of the s=±1 octupole bands have been discussed.
