Experiments on Yb 160 indicate three negative-parity bands up to I>~ 21 ℏ. All three
experience a band crossing around a frequency ℏ ω= 0.36 MeV, a value intermediate to
those of the first and second yrast backbends. The i 13 2 band in Yb 161 is observed up to
49 2+; it also has a strong upbend at this intermediate frequency. The fingerprint of a band
crossing based upon the crossing frequency and gain in aligned angular momentum is
demonstrated and the results compared to cranking-model calculations to suggest …

Abstract
Experiments on Yb 160 indicate three negative-parity bands up to I>~ 21 ℏ. All three experience a band crossing around a frequency ℏ ω= 0.36 MeV, a value intermediate to those of the first and second yrast backbends. The i 13 2 band in Yb 161 is observed up to 49 2+; it also has a strong upbend at this intermediate frequency. The fingerprint of a band crossing based upon the crossing frequency and gain in aligned angular momentum is demonstrated and the results compared to cranking-model calculations to suggest quasiparticle assignments for the bands.
