Abstract: 
A model of a quadrupole-octupole vibrating and rotating core plus a particle is proposed to describe and classify the quasi-parity-doublet spectra in odd-mass nuclei. The yrast levels are described as low-energy rotation-vibration modes built on the ground state. The non-yrast split parity-doublet sequences are considered as higher-energy rotation-vibration modes coupled to one-quasi-particle states. The even-even core is considered within the model of a coherent quadrupole-octupole motion, while the odd nucleon is described within the reflection-asymmetric deformed shell model with pairing interaction. The Coriolis decoupling and K-mixing interactions are calculated microscopically through a parity projection of the single-particle wave function. The unified model scheme was tested on the yrast and non-yrast quasi-parity-doublet spectra in the nuclei Ra-223 and Fr-221.
