Positrons can be used to study metallic defects. Positron annihilation experiments have been carried out to identify the defects in complex oxides. Positrons have also been used to study the Bose-Einstein condensation (BEC). Ps-BEC can be used to measure antigravity using atomic interferometers. Thi...
