Abstract
The -ray spectra from annihilations at rest have been measured with a 10-in.×10-in.-diam NaI(Tl) detector. The resolution of the system was ∼ 15% for -ray energies between 50 and 200 MeV. No clear evidence is found for monoenergetic rays with intensities greater than 1 per 30 annihilations.
