Abstract:
Electron-impact single ionization of W19+ ions has been studied both experimentally and theoretically. By employing the crossed-beams method, absolute cross sections have been measured in the energy range from the ionization onset up to 1000 eV. Theoretical calculations of the ionization-cross-section function were performed using the configuration-averaged distorted-wave method for electron-ion collision energies up to 150 keV. Contributions of excited long-lived primary-ion-beam admixtures were taken into account. The role of different competing ionization mechanisms contributing to the studied cross section is discussed. Plasma rate coefficients have been inferred and are presented in parametrized form.
