Electronic spectra of ArXe molecules in the region of Xe (6s', 6p, 5d), 77 000–80 200 cm−1, using resonantly enhanced multiphoton ionization

The excited electronic states of ArXe molecules in the region 77 000--80 200 cm-1 were studied using the (2+1) and (3+1) resonance-enhanced multiphoton ionization methods. The use of different methods of multi-photon excitation and Ar+ ion registration allowed us to obtain some new data. Molecular constants were obtained for previously unknown excited states of molecules with the following dissociation limits: ArXe* -> Ar1S0+Xe*6[character removed][5/2]3 with Delta *W = 2, 3 symmetry; Ar1S0+Xe*6p[3/2]2 with Delta *W = 1, 2 symmetry; Xe0S1 -> Xe*6s'[1/2]01 with Delta *W = 0+ symmetry.
