  One of the most striking findings in the recent high-spin spectroscopy is the
discovery of one-phonon, and possibly double-phonon, excitation of the nuclear
wobbling rotational bands. In this talk, we first review the properties of
observed wobbling motions, and discuss the failure and success of the possible
interpretation in terms of the simple rotor model. Then, we further present
results of our microscopic study in Hf and Lu nuclei by means of the
theoretical framework, the cranked mean-field and the random phase
approximation.
