We observe the total filling factor νT=1 quantum Hall state in a bilayer two-dimensional electron system with virtually no tunneling. We find thermally activated transport in the balanced system with a monotonic increase of the activation energy with decreasing d/ℓB below 1.65. In the imbalanced system we find activated transport in each of the layers separately, yet the activation energies show ...
