Mass-resolved two-photon and photoelectron spectra of ArXe in the region of Xe* 7p, 6p′, 6d

The two photon resonant, three photon ionization spectra of ArXe were recorded in the spectral 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′[3/2]2, Xe* 6p′[1/2]1, Xe* 6p′[1/2]0 have been selected and analyzed. The molecular constants for the excited states of ArXe* of these vibrational 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.
