摘要：

We calculate the effects of introducing muonium (a positive muon plus one electron) into trans-polyacetylene and cis-polyacetylene. We find that the energetically favoured site for the muon produces an sp3 hybridized carbon atom and an associated spin distribution. The spin is bound to the muon in cis-polyacetylene but is free to propagate in trans-polyacetylene. The presence of the muon acts as a barrier to the motion of mobile electronic defects.
