E(level): The 43- and 72-keV level energies are from 169Os α decay and all higher energies are from a least-square fit to γ-ray energies

Jπ(level): The assignments for high-spin (J|>13/2) are from 1992Si12 in (63Cu,p3nγ) based on the assumption of i13/2 for the lowest state populated in the heavy-ion induced reaction and also based on systematics of neighboring nuclei for negative-parity band heads. For higher states, ΔJ are suggested by the DCO ratios and band associations

M(γ): From DCO ratios in 106Pd(63Cu,p3nγ), unless otherwise stated
