E(level): Least squares fitted values from adopted γ-ray energies for levels populated in γ-ray studies. For levels populated in transfer reactions only, weighted average of available values taken.

E(level): In (3He,n), FWHM=500 keV, peaks are reported at 740 with L=(0), and at 2030(or 2330) and 3050 with L=(2), and at 3850.

Jπ(level): Parity not given when only a range of spin values given

T1/2(level): From ΔS(a) and recoil-Doppler shift method in in-beam γ, unless stated otherwise.

E(γ): Weighted average taken, whenever possible

I(γ): Photon branching ratios. Weighted average from various studies.

M(γ): From measured T1/2 of levels and RUL of Weisskopf estimates for transitions of E2 or M2 multipolarity.
