The Fermi-surface-deformation model is generalized to the case of a rotating nucleus. For solution of the equations of the model we have used the virial-theorems method of Chandrasekhar and Lebovitz. The shape parameters (in the approximation of oblate spheriods) and the eigenfrequencies of quadrupole vibrations of nuclei are calculated as a function of their rotational velocity ..cap omega... For ..cap omega.. = 0 the experimental values of the giant quadrupole resonance energy are reproduced. There are two low-lying modes of vibration in the model. The critical angular momenta are calculated. A comparison is made with the liquid-drop model.
