Simulation of emission spectra of the gas-discharge plasma of a krypton-xenon mixture

The narrow-band radiation observed in the range of the resonance line of xenon at 147 nm in the VUV emission spectra of the gas-discharge plasma of a krypton-xenon mixture is proposed to interpret as a manifestation of bound-bound transitions between the vibrational levels of the excited electronic states 0⁺(³ P ₁) and 1(³ P ₁) and the ground electronic state 0⁺(¹ S ₀) in the KrXe* molecule. A correction of the potential curves of the electronic states under consideration is proposed from a comparison of the calculated and experimental spectra.
