Description
Using a silica aerogel sample with oxygen gas introduced as the positronium source, the γ ray energy from the parapositronium 2γ annihilation has been measured as 510998.7 (2.5) eV by means of the comparison with the known γ energy 511856.2 (2.3) eV of the 106Ru γ ray. The result, after a revision of the binding energy of positronium, is comparied with the adjusted value of the electron rest mass published in several years ago
