Theoretical calculation of the transition spectra of highly charged tungsten ions in the EUV region

A relativistic atomic code, MCDF (Multi-Configuration Dirac-Fock), was used to calculate the transition probabilities of highly charged tungsten ions ranging from W33+to W37+. Transition probabilities at the wavelength range of 40-75 Å were obtained for the transitions from 4p54dn+1+4p64dn−1 4f to 4p6 4dn by using the electronic configuration of Mo ions.
