Electrochemical studies demonstrate that ∼300 ppm of charge (equal to the number of neutral solitons in undoped trans-(CH)x) is removed at mid-gap. These charges are transported through the polyacetylene electrode via hopping among states at the center of the energy gap, in agreement with Kivelson's theory. From analysis of the data, we have been able to determine the soliton creation energy, Es ≃ 0.5eV, which is in good agreement with the theoretical value, Es = (2/π)Δ.
