Abstract: 
A further extension of a model of coherent quadrupole-octupole vibrations and rotations and its application to alternating-parity spectra in heavy even even nuclei is presented. Within the model the yrast alternating parity sequence includes the ground state band and the lowest negative parity levels with odd angular momenta, while the non-yrast sequences include excited beta-bands and higher negative-parity levels. Electric transition operators reflecting the complex shape characteristics associated with the quadrupole-octupole vibration modes are introduced. By using them B(E1), B(E2) and B(E3) reduced transition probabilities within and between the different energy sequences are calculated. It is shown that the model successfully reproduces yrast and non-yrast alternating-parity bands together with the attendant B(E1)-B(E3) transition rates in the nuclei Sm-154, Gd-156 and Mo-100.
