General Comments:

All data and assignments concerning the excited levels and the γ’s are from the (HI,xnγ) studies. Thus, no level-specific Jπ arguments are given here. See the high-spin data set for comments. The 159Lu ε decay has been reported (1980Al14), but the γ’s have not been placed in the 159Yb level scheme.
