摘要: We report new measurements of the spectra argon, krypton and xenon in autoionization region using a two-step resonant laser excitation optogalvanic detection technique. By selecting (m)p5(m + 1)p'[3/2]2 as an intermediate state (m = 4, 5 6 for Ar, Kr Xe, respectively), we have been able to single out (m)p5nd[5/2]3 autoionizing resonances their spectra. The MQDT parameters derived from analysis series perturbations among (m)p5nd[5/2]3, (m)p5nd[7/2]3 (m)p5nd'[5/2]3 discrete phase shifted formulation three-channel quantum defect theory line profile above first ionization threshold. predicted reduced widths based on perturbation show good agreement with those experimentally observed profiles. Accurate values resonance energies, defects are reported.
