Excitation of Fe Ⅰ and Fe Ⅱ in electron-atom collisions

摘要

Excitation of the presumed laser levels of Fe Ⅰ and Fe Ⅱin electron-atom collisions is studied by the tecn- Niques of extended intersecting beams and optical spect- Roscopy. The total excitation cross sections for the z~5P°_3, X~5D°_4, and z~5F°_5 levels of the iron atom were determined. The excitation cross sections were measured for transitions Arising from the odd levels of Fe Ⅱ with an excitation energy Ranging from 38 000 to 48 000 cm~-1 relative to the ground Level of Fe Ⅱ.
