With use of the ordinary quadrupole-quadrupole (Q-Q) interaction, a total splitting of the K=0, 1, 2 components in the giant quadrupole resonance (GQR) of about 6 MeV is predicted for deformed $sup 154$Sm. A 0.8plus-or- minus0.3-MeV broadening of the GQR is observed for $sup 154$Sm relative to spherical $sup 144$Sm with inelastic $alpha$ scattering. A model requiring rigorous self-consistency is proposed which modifies the Q-Q interaction, reduces the predicted splitting to about 2 MeV, and removes inconsistencies in the strength of the interaction for K=0 and K=2 components in low-lying $beta$ and $gamma$ bands.
