摘要

We have analyzed the narrow components in the positron annihilation angular correlation spectra of graphite-potassium intercalation with the theoretical formula, which is extended from “topological quasi-positronium” model and discusses the relation to the catalytic activity of hydrogens. One mechanism of the soliton-catalytic effect is proposed.
