Single particle and vibrational bands in 155Gd, 161Dy, and 163Dy

The nuclei 155Gd, 161Dy and 163Dy have been investigated by means of the (n, γ), (n, e) and transfer reactions. Level schemes have been constructed up to about 1.5 MeV, which include spin and parity assignements for many levels. New rotatinal bands based on single particle states (Nilsson) as well as on vibrational states have been identified. The results are discussed.
