Electron-impact ionization of W9+ and W10+

doi:10.1088/1674-1056/aca14d

Abstract Electron-impact single-ionization (EISI) cross sections for W$^{q+}$ ($q=9$, 10) ions have been calculated by using the level-to-level distorted-wave (LLDW) method with emphasis on the contribution of metastable states to the total ionization cross sections. Contributions from direct-ionization (DI) and excitation-autoionization (EA) processes are taken into account. The calculated cross sections include the contributions from both the ground configuration and the long-lived metastable states with lifetimes exceeding 10$^{-6}$ s. Calculated cross sections are in good agreement with experimental measurements when the influence of metastable states on the total ionization cross section are well considered.
