NEW LOCALIZED ELECTRONIC STATES OF SOLITON IN TRANS-(CH)_x

It is well known that the soliton in trans-(CH)_x possesses a localized electronic state at the center of the gap. Besides this mid-gap state, we have found that there exist another four localized electronic states around the soliton. They form four discrete levels outside the conduction and valence bands: one sits near the bottom edge of the conduction band and one near the top edge of the conduction band; another two are located symmetrically near the valence band.
