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

摘要

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* → Ar ~1S_0 + Xe* 7p1/2_0, Xe* 7p3/2 _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.
