General Comments:

Evaluators assumed that the low-spin level is the ground state. However, the high-spin level could well be the ground state

E(level): From least-squares fit to Eγ, assuming that the energy of the two isomers is equal to zero. The uncertainties in the energy of the isomers was not propagated.

Jπ(level): Values assigned through systematics of adjacent Tb, Dy and Ho nuclei, and shell-model predictions.
