A method of determination of the partial cross-sections for the ion ionization by electron impact is described. The absolute values of s- and d-ionization cross-sections for In+ ions were found to equal 2.1×10^−17 and 5.2×10^−17 cm2, respectively. The results obtained testify to the important role of the excitation-autoionization process that makes a substantial contribution to the electron-impact ionization cross-section of ions. |
