Abstract
The branching ratio method is used to carry out a determination of the quantum efficiency of a vacuum UV spectrometer at discrete wavelengths between 37.9 nm and 73.6 nm. Branching ratios of ion impact excited Ne III and Ne IV are applied. Cross sections for the ion and electron impact induced 2s-vacancy production in neon are determined.
