Description
In the core-particle coupling scheme, a collective model is proposed to describe high-spin phenomena in the triaxial odd-A and odd-odd systems with their even-even cores assumed to follow a critical point symmetry. It is shown that the model Hamiltonian can be approximately solved with the solutions being expressed in terms of the Bessel functions of irrational orders, which in turn generate a dynamical structure involving collective multiple chiral doublets bands or wobbling bands. An example for $^{132,133}$La will be discussed.
