The level structure and grouping into quasibands of /sup 154/Dy and /sup 156/Dy is derived in the dynamic pairing-plus-quadrupole model and the analysis is extended to five quasibands in /sup 154/Dy and seven collective K bands in /sup 156/Dy. The absolute E2 moments, relative B(E2) values for interband transitions and X(E0/E2) are compared with experimental data and the predictions from the boson expansion model and the interacting boson model. The transition at N = 88--90 for all observed quantities is reproduced. The anomaly of small 0/sub g/-2/sub ..beta../ strength in /sup 156/Dy is explained from our analysis, retaining the collective ..beta..-vibration character.
