The time-of-flight of positronium emitted from single-crystal and amorphous (Formula presented) has been measured using a high-intensity pulsed positron beam at KEK. For both the samples, two components of peak energies around 1 and 3 eV have been observed. They are attributed to the Ps formed in the bulk and on the surface of the (Formula presented) respectively.
