Cross Sections for Excitation and De-Excitation Processes among ³P₂, ³P₁, ³P₀, ¹D₂ and ¹S₀ of Ne²⁺ and Ar²⁺ in Collisions with Rare Gases

Abstract

Cross sections for excitation and de-excitation in Ne²⁺ and Ar²⁺ have been measured with a high resolution translational energy spectrometer. For Ar²⁺, the cross sections for the transitions ³P₂↔³P₁, ³P₂↔¹D₂ and ¹D₂↔¹S₀ have been measured in collisions with He and Ne in the energy range from 0.8 to 5 keV. For Ne²⁺, no peak due to the transitions has been observed.
