The ground states [Ne]3s 23p 63d 2 and first excited states [Ne]3s 23p 53d 3 of W54+ ion have been studied by using Multi-Configuration Dirac-Fock method with the implementation of Grasp2K package. A restricted active space method was employed to investigate the correlation contribution from different models. The Breit interaction and QED effects were taken into account in the relativistic configuration interaction calculation with the converged wavefunction. It is found that the correlation contribution from 3s and 3p orbital have important contribution to the energy level, transition wavelength and probability of the ground and the first excited state of W54+ ion.}, title = {Correlation, Breit and Quantum Electrodynamics effects on energy level and transition properties of W54+ ion}, volume = {71}, year = {2017} }
