General Comments:

The data are primarily from the (HI,xnγ) studies.

Levels: 1988KlZX report an average g-factor=0.20 7 for states above the second backbend in 158Yb by the method of integral spin precession on unresolved transitions in a transient magnetic field with an average J=38 and and spanning the interval ΔJ=4.

Levels: See the (HI,xnγ) for six levels not included here.

Q-value: Q(ε)=2690 3, S(2n)=18887 13, S(2p)=6380 3 Q(εp)=110 3

E(level): From γ energies.

Jπ(level): From authors and based on assigned band structure, on theory calculations and systematics (similar to 156Er), based on the unique parity orbitals νi13/2 and πh11/2

T1/2(level): Values for excited levels are from (HI,xnγ) study (1975Tr08).
