Abstract

Effects of quantum fluctuations, like wobbling and γ-fluctuations, are examined in even- as well as in odd-particle systems by making use of a simple model based on the Bohr hamiltonian. The strong signature dependence observed in ΔI = 1 E2 transitions in odd nuclei is studied in the context of an axially asymmetric deformation. We point out the importance of the quantum fluctuations especially at low-spin values and / or for shapes with small deviations from axial symmetry. It is also demonstrated that the J(2) moment of inertia may be larger than J(1) due to the wobbling motion.
