Abstract
By simultaneous measurements of the attenuation and velocity of surface acoustic waves propagating in proximity to a high-quality GaAs quantum well we study the complex AC conductance of the two-dimensional electron system. Focusing on the vicinity of the filling factor ν=1/5 we confirm that the insulating states formed closely to this value of ν are pinned Wigner crystals.
