K alpha transition probabilities of C-like to F-like Al ions

摘要

K alpha radiative transitions of C-like to F-like Al ions are studied using the multiconfiguration Dirac-Fock (MCDF) method. The fully relativistic MCDF approach was specifically designed to calculate atomic structures and radiative transition rates, and hence it ensures a reasonable description of the emission effects and spectral intensities. The energies and wavefunctions, corresponding mixing coefficients, the influence of electron correlation effects on energy levels, and radiative transition rates for C-like to F-like Al ions are investigated in detail. Good agreement is found between the calculated K alpha emission spectra in this work and the spectra from experimental measurements.
