Multiconfigurational Dirac–Fock energy levels and radiative rates for Br-like tungsten

Abstract

Energies, lifetimes, and wavefunction compositions have been computed for all levels of odd parity 4s24p5 ground configuration and 3d94s24p6 excited configuration as well as 4s4p6 and 4s24p44d even parity excited configurations in highly charged Br-like tungsten ion (W XL) by using the multiconfigurational Dirac–Fock method. Also, we have reported the transition wavelengths, oscillator strengths, transition probabilities and line strengths for the electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transition from the 4s24p5 configuration. We have compared our calculated results with the other available experimental and theoretical results. The excellent agreement observed between our new results and those obtained using different approaches confirm the quality of our results.
