Microscopic calculations of the low-lying and high-lying K/sup ..pi../=0/sup +/, 1/sup +/, and 2/sup +/ states in deformed rare-earth nuclei have been performed. The centroids of the isoscalar giant quadrupole resonance in /sup 160/Dy, /sup 170/Yb, and /sup 184/W are at 11.58, 11.44, and 11.22 MeV, respectively. A broadening of these resonances due to the deformation is predicted which varies appreciably in the different nuclei. About 20% of the monopole strength is found in the same energy range. (AIP)
