Abstract

Electronic states and depolarization phenomena are studied for theμ + in cis- and transpolyacetylene (CH)x. Formation of weakly bound muonium-like paramagnetic state is found in cis-(CH)x at room temperature, while diamagneticμ + state is formed in trans-(CH)x. The origin of this clear difference might reflect properties of excitation modes in these two-isomers.
