The angular correlation of photons from positrons annihilating in NaF and NaCl at 300 K and 84 K has been measured. Narrow component which is characteristic of the annihilation of electron-positron pairs in a positronium-like statel has been observed on the angular correlation curves for the two alkali halides at 84 K.
