Measurement of HgXe excimer potentials

Abstract

The HgXe excimer band at 270 nm has been studied in fluorescence following optical excitation of the Hg ³P₁ level. From the temperature dependence of the normalized fluorescence band shape, the potential curves of the ³O⁺ excimer state and the ¹O⁺ ground state are inferred. A binding energy of 1400±100 cm⁻¹ is found for the ³O⁺ state.
