Giant quadrupole resonance in rotating light nuclei in the calcium region
The quadrupole vibrations of rotating light nuclei around calcium are analyzed in the framework of the Fermi liquid drop model. The input parameters of shape and deformation are those obtained by the Mottelson-Nilsson method for the rotating light nuclei. The surface diffuseness and its changes with spin which could affect the giant resonances in the light nuclei are automatically taken care of in this method. The experimental energies of the giant quadrupole resonance are reproduced in the Fermi liquid drop model for the nonrotating case. The rotation produces the expected splitting of the giant quadrupole resonance modes with the appearance of soft modes. The nature of such splitting may explain the observed changes in the widths of giant resonances at high spins.
