Excited states in 164Dy were produced using Coulomb excitation. Rotational properties of the ground-state and gamma-vibrational band were studied. Angular distribution and band-mixing parameters were extracted from the data. No evidence was found for a two-phonon gamma vibration with anharmonicity in the range 1.7≤E(4γγ+)/E(2γ+)≤2.7.
