Abstract

We have analyzed the narrow components in the positron annihilation angular correlation spectra of stage-2 graphite-potassium intercalation by using the topological charge density of the skyrmion-like soliton, and have discussed the energy loss rate for low-energy positrons through “topological quasi-positronium” effect.
