Generalized Gradient Approximation

Abstract content <br>   (Max 300 words)
High momentum components of positron-electron annihilation radiation are in general related to the annihila- tions of core electrons with positrons. A theoretical approach is conducted to study the contributions of low to high momentum components of electron-positron momentum density in ionic barium flouride. Annihilation rates are calculated within the Independent Particle Model (IPM) and Generalized Gradient Approximation (GGA). Defect and defect-free zones annihilation rates are also considered.
