Advanced relativistic many-body atomic calculation of electric dipole transition.

Utilising GRASP for ab initio calculation and performed spectral analysis and fitting of the zinc Kb emission spectrum.

My Master's research focused on ab initio modelling of the zinc Kb emission spectrum using GRASP. This work involved calculating both the main diagram and the dominant shake-off satellite transitions spectra from first principles. I developed and employed convergence metrics to assess the accuracy and stability of the calculations. The shake-off probabilities for zinc were determined and used as relative intensities for spectral fitting to the experimental data. Detailed spectral analysis was performed to investigate the origins of line asymmetries and satellite structures. This research has led to the submission of a first-author paper to Journal of Physics B. 

My proposed PhD research aims to investigate atomic transitions both experimentally and theoretically, with focus on relativistic interactions and quantum electrodynamic corrections. The project will involve the study of gauge invariant multipole transition amplitudes, self-energy and vacuum polarisation corrections, and relativistic electron-electron interactions.
