Jπ(level): Jπ assignments are based on experimental L-values from 175Yb(t,p) and on band structure systematics of lighter even-Yb isotopes. L-values are given with individual levels.
E(γ): γ-ray data from (HI,Xγ) deep inelastic reaction dataset.

278.0 | 4+ | E(level): Kπ=0+ GS ROTATIONAL band. | |
578.1 | (6+) | E(level): Kπ=0+ GS ROTATIONAL band. | |
981.3 | (8+) | E(level): Kπ=0+ GS ROTATIONAL band. | |
1221 | (2+) | E(level): Kπ=2+ γ-vibrational band. | |
1315 | 0+ | E(level): Kπ=0+ band. | |
1387 | (2+) | E(level): There is some ambiguity about the identity of the 2+ member of the excited Kπ=0+ band. Both the 1387 and the 1404 keV levels have been proposed; see comment in the (t,p) reaction dataset. | |
1404 | 2+ | E(level): Kπ=0+ band. There is some ambiguity about the identity of the 2+ member of the excited Kπ=0+ band. Both the 1387 and the 1404 keV levels have been proposed; see comment in the (t,p) reaction dataset. | |

2080 | (12+) | E(level): Kπ=0+ GS ROTATIONAL band. | |
2131 | (4+,5-) | Jπ(level): The Jπ assignment should be considered tentative; see comments in the (t,p) reaction dataset. | |
2770 | (14+) | E(level): Kπ=0+ GS ROTATIONAL band. |
Levels: Level energies derived from proton spectra in 176Yb(t,p) reactions (1983Bu03,1982Zu02), and γ-ray data from 176Yb(48Ca,Xγ) and 176Yb(154Sm,Xγ) deep inelastic reactions (1997Le11,1999As05).
