Abstract:

On the basis of the concept of spontaneous breakdown of the rotation symmetry in the deformed Hartree-Fock-Bogoliubov minimum as the origin of the nuclear collective rotation, the self-consistent collective coordinate (SCC) method is applied to disclosing occurrence mechanism of the collective rotation. Through the intermediary of the SCC method, a manifest relationship between Marshalek and Weneser's full quantum theory of rotational motion and the conventional cranking model approach is given. In order to reveal how the so-called rotation-vibration coupling effects are coherently organized so as to construct a global optimum subspace of collective rotation, a set of basic equations of the SCC method is solved for the low-spin ground-state rotational bands of Er isotopes. Systematic features of microscopic structure of rotation-vibration couplings are investigated in detail.
