Abstract

In the sequel of the present study, we have investigated the rotational motion of triaxially deformed nucleus by using the microscopic framework of angular-momentum projection. The Woods-Saxon potential and the schematic separable-type interaction are employed as a microscopic Hamiltonian. As the first example, nuclear wobbling motion was studied in detail in part I of the series. This second part reports on another interesting rotational mode, chiral doublet bands: two prototype examples, Cs128 and Rh104, are investigated. It is demonstrated that the doublet bands naturally appear as a result of the calculation in this fully microscopic framework without any kind of core, and they have the characteristic properties of the B(E2) and B(M1) transition probabilities, which are expected from the phenomenological triaxial particle-rotor coupling model.
