抄録

Positrons injected into alkali metal-intercalated cup-stacked carbon nanofibers convert to positronium (Ps) atoms with a quite high yield of ca. 25%, which is insensitive to insertion of alkali metal intercalant layers and charge transfer from alkali metal to graphene sheets. The high yield is ascribed to the formation of Ps in voids distributed in a large quantity on edge-planes (not on sheet-planes) of graphite materials.
