Absolute Cross-Sections of s- and d-ionizations of In+ Ions at Their Collisions with Slow Electrons
Section: Atoms and molecules
Original Author's Text: Ukrainian
Abstract: Effective cross-sections of s- and d-ionization of In+ ions by electron impact have been studied using a spectroscopic technique, when the ion and slow-electron beams cross each other at the right angle. 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.
Key words: indium, electron-ion collisions, ionization with excitation, partial cross-sections of ionization, excitation-autoionization.
