| Summary: | In this manuscript, we present our calculations of detailed electron-impact single ionization cross-sections for tungsten ions, spanning charge states W<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mrow><mn>38</mn><mo>+</mo></mrow></msup></semantics></math></inline-formula>− W<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mrow><mn>45</mn><mo>+</mo></mrow></msup></semantics></math></inline-formula>. The level-to-level distorted-wave method implemented in the flexible atomic code (FAC) was used for calculation. Comparison between the present level-to-level distorted wave treatment and previous configuration-averaged calculations has been performed for the W<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mrow><mn>45</mn><mo>+</mo></mrow></msup></semantics></math></inline-formula> ion, and we explore the possible reason for the difference observed between two calculations. We demonstrate the importance of radiative damping on the total electron-impact ionization cross-section for the W<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mrow><mn>43</mn><mo>+</mo></mrow></msup></semantics></math></inline-formula> ion. Present calculations provide missing cross-sections for W<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mrow><mn>38</mn><mo>+</mo></mrow></msup></semantics></math></inline-formula>− W<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mrow><mn>45</mn><mo>+</mo></mrow></msup></semantics></math></inline-formula>. The data obtained are expected to be useful for modeling plasmas for fusion applications, especially for the ITER community.
