“…Formulas for the changes in resonance structures caused by the channel coupling of two autoionizing Rydberg series under perturbation by an interloper were obtained and applied to the experimental data reported in Refs. [11] and [12]. This work continues these previous studies of analysing resonance structures in complex spectra by decoupling the interloper's spectrum from the autoionizing Rydberg series.…”

The resonance structure of the preionization spectrum of H 2 in the region immediately above its H 2 + ionization threshold, converging toward its rotationally excited limit, is complicated due to perturbation by the vibrationally excited levels 7pπ v = 1 and 5pπ v = 2. The spectra of interlopers are separated from the rotationally preionizing Rydberg series to allow analysis of this complex resonance structure. Although only two vibrationally excited levels perturb the rotational preionization spectrum, at least 6 interloper Rydberg series participate in the complex spectrum over most of its energy range and more interloper series participate at a narrow range around 124500 cm −1 in the spectrum. To allow handling of an arbitrary number of interloper series, MATLAB ® 's symbolic operation is used to perform on-the-fly formulation.

“…Let us apply the theory to the narrow 6p1/2,3/2np J = 1 autoionizing Rydberg series in barium perturbed by the 6p 3/2 nf states obtained in Ref. [19]. They used 5d 3/2 6p 3/2 3 P 0 as an intermediate level to excite the 6pnl J =1 autoionizing Rydberg series.…”

“…Numerous spectra belonging to this null indirect coupling case have been observed, particularly by Hogervorst's group. [16][17][18][19] One of their spectra will be considered in the next section. They applied extensively the concept of assigning one effective continuum to one closed channel proposed by Cooke and Cromer.…”

“…The present theory was applied to the narrow 6p 1/2,3/2 np J = 1 autoionizing Rydberg series in barium perturbed by the 6p3/2nf states obtained by de Graaff et al, 19 which is one of the series of experiments that applies the concept of assigning one effective continuum to one closed channel proposed by Cooke and Cromer. 4 The experiment corresponds to the case of null indirect coupling between the closed channels in our theory.…”

Previous work on the phase-shifted version of the multichannel quantum-defect theory (MQDT) for a system involving 2 closed and many open channels (Lee, C.-W. Bull. Korean Chem. Soc. 2010, 31, 1669) was extended to obtain the formulae of the spectral shape parameters with the structure of a pole extracted explicitly for general cases only limited by 2 non-degenerate closed channels. The theory was applied to the narrow 6p1/2,3/2np J = 1 autoionizing Rydberg series in barium perturbed by the 6p3/2nf states obtained by de Graaff et al.
