Speaker

Mr Thulani Jili (University of Zululand)

Would you like to <br> submit a short paper <br> for the Conference <br> Proceedings (Yes / No)?

Yes

Abstract content <br> &nbsp; (Max 300 words)

High momentum components of positron-electron annihilation radiation are in general related to the annihilations 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.

Apply to be<br> considered for a student <br> &nbsp; award (Yes / No)?

No
