Abstract

O₂⁺ ion desorption as a reaction product from solid CO₂ ice has been observed for the first time. The desorption threshold is at the ionisation potential for solid CO₂, ~6 eV below that for O₂⁺ production in the gas phase. The threshold for CO⁺ ions is also substantially below the gas phase threshold. No positive ion desorption has been seen at or below the solid ionisation threshold in any condensed gas before. Both solid threshold energies are a result of multielectron excitations.
