Bands in Er161 have been identified up to 50 hbar.
Tentative evidence is found for unpaired band-crossings in two of the bands.
This is consistent with recent cranking calculations which predict the existence of steeply aligning bands, which cross the lower-lying bands at the spins observed. Future plans involve carrying out similar measurements for 159,160Er to investigate unpaired band crossings and band termination as a function of neutron number.
