Jπ(level): For the lowest members of the bands reported in the in-beam study (1982Be46), Jπ=9- and 7+ have been assumed (1982Be46), with the 9- proposed in analogy to a 9- band in 152Eu and the 7+ in analogy to the one in 156Tb.
Jπ(level): Within the 9- and 7+ bands, the spins and parities are assigned from the apparent band structure and the stretched E2 character for some γ’s.
E(γ): For unplaced γ’s, see the in-beam data.
