Abstract
A formalism has been developed for calculating positron-annihilation characteristics in perfect solids and solids containing defects taking into account the effects of electron-positron correlation self-consistently. The lifetime and two-dimensional angular-correlation spectra have been calculated for positrons annihilating in defect-free aluminum and are in excellent agreement with experiment.Keywords
