Abstract
Doppler-broadening measurements have been made on the 511-keV photons resulting from positron annihilation in annealed and plastically deformed samples of indium, zinc, cadmium, and gold. Over the temperature range 4-400 K, distinctive features are observed in each case. Studies with a single crystal of cadmium associate the features with defects at grain boundaries.Keywords
