    "abstract": "We construct a three-dimensional analytically soluble model of the nonlinear\neffects in Coulomb excitation of multiphonon Giant Dipole Resonances (GDR)\nbased on the SU(2,1) algebra. The full 3-dimensional model predicts further\nenhancement of the Double GDR (DGDR) cross sections at high bombarding\nenergies. Enhancement factors for DGDR measured in thirteen different processes\nwith various projectiles and targets at different bombarding energies are well\nreproduced with the same value of the nonlinearity parameter with the exception\nof the anomalous case of $^{136}$Xe which requires a larger value.",
