Spectra of the W25+ ion are studied using the collisional-radiative model (CRM) with an ensuing cascade emission. It is determined that the cascade emission boosts intensities only of a few lines in the 10–30nm range. The cascade emission is responsible for the disappearance of structure of lines at about 6nm in the electron beam ion trap plasma. Emission band at 4.5–5.3 nm is also affected by the...
Energy levels and emission spectra of W 25+ ion have been studied by performing the large-scale relativistic configuration interaction calculations. Configuration interaction strength is used to determine the configurations exhibiting the largest influence on the 4f 3 , 4d94f4, 4f25s, 4f25p, 4f25d, 4f25f, 4f25g, and 4f26g configuration energies. It is shown that correlation effects...
