Description
High spin states in 139Xe and 141Ba have been investigated using γ-γ - and γ-γ-γ-coincidence studies of spontaneous fission of 252Cf. Alternating parity bands built on a 7/2-level are assigned up to spin I=(37/2) and I=(29/2) in 139Xe and 141Ba, respectively. Another possible octupole band based on νi132(f7/2)2 multiplet with spin up to (29/2) also is observed in both nuclei. Cascades of enhanced E1 transitions and B(E1)/B(E2) ratios indicate strong octupole correlations. Systematics of the ν(f7/2)3, ν(f7/2)3x3- and νu13/2(f7/2)2 multiplets and bands in N 85 isotones are presented. (author). Letter-to-the-editor
