The Influence of Triaxial Deformation and Quasiparticle Alignment on the Structure of Chiral Partner Bands

Abstract

The spectrum and wave-functions of chiral partner band states are investigated within a semiclassical treatment of a particle-rotor Hamiltonian with rigid quasiparticle alignments [1]. The study focuses on the variation of spectral characteristics and associated dynamics inferred by considering different triaxial deformation of the core [2] or non-axial quasiparticle alignments with arbitrary tilting [3]. The analysis is performed for valence h11/2 proton particle and h11/2 neutron hole alignments. As a result, distinct dynamical characteristics are identified in specific angular momentum ranges, especially concerning the chiral vibration regime.
