- Title
Excitation of Even Triplet Levels of YII in the e–Y Collisions.
- Authors
Smirnov, Yu. M.
- Abstract
The excitation of high-lying triplet levels of a singly charged yttrium ion by electron-atom collisions is studied experimentally. The parity of the levels studied coincides with the parity of the initial state YI. Forty one excitation cross sections with simultaneous single ionization are measured for an exciting electron energy of 50 eV. The optical excitation functions (OEF) are recorded for the majority of transitions in the electron energy range 0-200 eV. The total cross sections are determined for 20 energy levels. Possible channels of a simultaneous excitation-ionization process are discussed.
