E(level): For levels from 154Lu IT decay, values are computed from a least-squares fit to the γ-ray energies and are relative to the energy of the lower (9+) level. The uncertainty given with each level is for the relative energy only; the total uncertainty should include the uncertainty of its bandhead. The energy of the lower (9+) level is from the 158Ta α decays (1997Da07).

Jπ(level): Unless noted otherwise, the Jπ and configuration assignments for the levels above 70~keV are those suggested from 154Lu IT decay (1990Mc02) and are based on analogy to those in 150Ho and 152Tm.
