The electron correlation and soliton in polyacetylene have been studied with the CBF method. By considering the complete electron-electron interaction, we concluded that the stable static configuration of a PA chain with odd atoms and a single electric charge is a soliton. With the increase of e-e interaction strength U and interaction range α/β the localization of soliton is enhanced, and the soliton creation energy is reduced, so although the e-e interaction is considered, the conclusion that soliton is main charged carrier in high conducting polymers is still tenable.
