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

R. Budaca
Abstract. The chiral partner bands are investigated within a semiclassical treatment of a particle-rotor Hamiltonian with rigid quasiparticle alignments. The study focuses on the variation of spectral characteristics and associated dynamics inferred by considering different triaxial deformation of the core or non-axial quasiparticle alignments with arbitrary tilting. The analysis is performed for a valence h11/2 particle and h11/2 or g9/2 hole alignments. As a result, distinct dynamical characteristics are identified in specific angular momentum ranges, especially concerning the chiral vibration regime.
