A search for the double-γ vibration is performed using thermal neutron capture on 163Dy. A level at 2173 keV in 164Dy is found to exhibit a collective enhancement in its decay to the single-γ vibration, suggesting a contribution from the Kπ=4+ double-γ excitation. Both its energy and the measured B(E2) value to the single-γ vibration are in reasonable agreement with the different theoretical predictions.
