Outer shell excitations of He and Ne using projectiles of C⁺, N⁺, O⁺, F⁺,²⁰Ne⁺,²²Ne⁺, Na⁺ and Mg⁺

Abstract

He and Ne have been bombarded with singly charged ions of elements from carbon to magnesium, in the energy range 10–75 keV, and photons emitted from the target atoms have been detected. The results are discussed in terms of molecular orbital level correlation diagrams in which account has been taken of conservation of the total electronic spin. Comparisons are drawn with inner shell excitations and electronic stopping power measurements.
