  The model of coherent quadrupole and octupole motion (CQOM) is applied to
describe non-yrast split parity-doublet spectra in odd-mass nuclei. The yrast
levels are described as low-energy rotation-vibration modes coupled to the
ground single-particle (s.p.) state, while the non-yrast parity-doublet
structures are obtained as higher-energy rotation-vibration modes coupled to
excited s.p. states. It is shown that the extended model scheme describes both
the yrast and non-yrast quasi parity-doublet spectra and the related B(E1) and
B(E2) transition rates in different regions of heavy odd-A nuclei. The
involvement of the reflection-asymmetric deformed shell model to describe the
single-particle motion and the Coriolis interaction on a deeper level is
discussed.
