| Zusammenfassung: | <jats:p>We study the manifestation of collective vibrations and rotations coupled to single-particle motion in odd-mass nuclei with the presence of axial quadrupole-octupole deformations. Our model incorporates <jats:italic>K</jats:italic>-mixing effects stemming from the Coriolis interaction between the odd nucleon and the even-even core and thus takes into account the probabilities for otherwise forbidden due to the axial symmetry electromagnetic transitions between excited states built on different intrinsic configurations. We demonstrate these effects in the quasi-parity-doublet spectrum of the nucleus <jats:sup>221</jats:sup>Fr in which a strong Coriolis interaction manifests. The model successfully describes the available intra- and interband <jats:italic>E1</jats:italic>, <jats:italic>E2</jats:italic> and <jats:italic>M1</jats:italic> transition rates giving an insight into the mechanism which allows the <jats:italic>K</jats:italic>-suppressed transitions in axially symmetric nuclei.</jats:p> |
