Abstract

"The technique of heavy-ion energy-loss spectrometry has been used to measure excitation cross sections for the (2p⁵)3s and (2p⁵)3p electronic configurations of Neon. The incident particles used were H⁺ , H⁺₂ and He⁺ at impact energies from 20-180 keV. The results are compared with previous optical measurements of the emission cross sections of lines from these levels as excited by H⁺ and He⁺ impact. Agreement is not good, either in shape or in absolute magnitude for excitation of the (2p⁵)3s configuration. However, agreement is surprisingly good for excitation of the (2p⁵)3p configuration. A curve fitting technique has been applied to extract relative singlet-triplet cross sections for levels within the (2p⁵)3s configuration. Almost no triplet excitation is observed for H⁺ and H⁺₂ impact. The former is expected while the latter is somewhat surprising. Significant triplet excitation is observed only for He⁺ impact"--Abstract, page ii.
