  The coupling of the high-lying dipole mode to the low-lying quadrupole modes
for the case of deformed gamma-unstable nuclei is studied. Results from the
geometrical model are compared to those obtained within the dipole boson model.
Consistent results are obtained in both models. The dipole boson model is
treated within the intrinsic frame, with subsequent projection onto the
laboratory frame. As an application, calculations of photonuclear
cross-sections in gamma-unstable nuclei are presented.
