Coriolis coupling effects in giant resonances on rotating nuclei

Giant resonances on high spin states are described as scaling solutions of a linearized Vlasov equation in a rotating frame. Apart from effects of dynamical deformations we obtain a further splitting of the giant resonance due to the Coriolis coupling just through an approximate choice of the scaling which takes into account the shift of the Fermi sphere due to the rotation. Results are shown for 168Er. From the evaluation of the EM strengths we predict a small shift of the GR centroid to lower energy with increasing angular velocity. (orig.)
