The two photon resonant, three photon ionization spectra of ArXe were recorded in the spec-
tral region of 88 500–90 100 cm−1. Seven new molecular band progressions dissociating to
ArXe∗ → Ar1S0 + Xe∗ 7p[1/2]0, Xe∗ 7p[3/2]2, Xe∗ 6p
been selected and analyzed. The molecular constants for the excited states of ArXe∗ of these vibra-
tional progressions were determined in the approximation of the anharmonic oscillator, the Morse potential and the Franck-Condon principle. The photoelectron spectra were recorded by several excited electronic-vibrational transitions of ArXe, the dissociation channels of the excited molecules
were determined and extra information about the electron structure of the excited molecular states
was obtained.
