Description

A system composed of a triaxial core with non-axial rigid quasiparticle alignments is investigated in a semiclassical approach. The classical features of the chiral geometry and wobbling motion emerging in atomic nuclei and the associated dynamics are investigated for various core deformations and single-particle alignments. Distinct dynamical characteristics are identified in specific angular momentum ranges, triaxiality and alignment conditions. Quantum observables are recovered from a Schroedinger equation, constructed from the classical picture, which has the total angular momentum projection as a continuous variable. The separation of a potential energy as a function of the chosen variable allows the phenomenological interpretation of the experimental spectra in terms of wobbling or chiral oscillations and tilted axis rotations.
