J^π(level): Levels at 495 10, 520 10, 560 10, and 620 10 are reported in (d,d’) and suggested by the authors, 1972Br46, to be part of a rotational band built on a vibrational state. Levels at 519 and 561 are known from β^- decay, and 1998Wh01, in (n,γ), propose that these levels are the bandhead and first-excited state of a band with configuration 5/2[622]~#0-. They further propose that the 9/2- member of this band lies at 615 keV, deexciting via a 573γ. No correspondence in (n,γ) with the 495 (d,d’) level has been found. These levels decay only to the g.s. 5/2[622] band and are expected to have mult=E1; however, except for the 518.8γ, the α(K)exp values measured by 1998Wh01 in (n,γ) are all larger than the theoretical E1 value and require some M2 admixture. For the 561.44γ and 572.86γ, in fact, α(K)exp is larger than the E2 value. For consistency with the proposed configuration, the mults for the 561 and 572γ’s are assumed to be E1⁺M2 rather than M1⁺E2.

800.443	758.494	E(γ): The authors report E=758.494 15 doubly placed from the 800.44 and 800.48 levels. Iγ/Iγ(638.8γ)=0.349 16 and Iγ/Iγ(629.5γ)= 0.253 11, respectively for these two placements. These transitions are not included in the least-squares fit. For these placements, the least-squares fit gives Eγ=758.470 6 and Eγ=758.506 6, respectively I(γ): The authors report E=758.494 15 doubly placed from the 800.44 and 800.48 levels.

E(level)	E(gamma)	Comments
897.503	726.562	M(γ): α(K)exp is consistent with the E2 theory value; however, placement in the level scheme requires Δπ=yes. See footnote on Jπ for the 897.5 level
1223.841	444.687	M(γ): See comment on Jπ(1224 level)
1223.841	1052.93	M(γ): See comment on Jπ(1224 level)
