Abstract
A computational technique is developed to evaluate positron distributi on as well as the electron-positron momentum densities in diamond and the use of these provide us the means of interpreting the k-space dens ities obtained experimentally using the two-dimensional angular correl ation of annihilation radiation (2D-ACAR). The method is based on the independent particle approximation (IPM) coupled with the empirical ps eudopotential method (EPM) including a non-local correction. Results s how a fairly good agreement with the experiments.
