Two new types of behavior have been observed in /sup 156/Er. The first is a terminating band ending on a 42+ fully aligned state. The second is a strong cross feeding among four negative parity bands, due most likely to a severe reduction or collapse of the neutron pairing. In /sup 158/Er we have found two sequences feeding the 38+ level; one slow and one fast. This suggests that some feeding goes through regions of oblate (or nearly so) shapes, and some does not. Lifetimes have been determined for levels around 30+ in /sup 166/Yb, which seem to be longer than is easily explained. 23 refs, 8 figs.
