The many channel quantum defect theory (MQDT) has been proposed as a semiempirical tool for the calculation of mixing coefficients between interacting Rydberg series in atoms and ions. We have examined the fitting procedure and estimated the deviations on the parameters of MQDT.It is found that the parameters in general are rather badly determined and that the mixing coefficients are rather ambigious. Results for some two and three valence electron systems are presented. It is shown that MQDT cannot be used together with coulomb approximation methods to calculate lifetimes in the B I and A1 I homologeous systems as the mixing coefficients of MQDT are greatly in error.

“…This procedure has been shown to give accurate lifetimes in the Ga I and In I atoms [12], systems for which other semi-empirical methods are difficult to apply [13]. The numerical approximation has been shown to give very accurate results for one-electron systems such as Li I and its isoelectronic sequence [14] both for the neutral end and the highly ionized species.…”

Energy Levels and Transition Probabilities in Mo XIV

et al. 1977

An investigation is made of the energy levels in Mo XIV (Cu I isoelectronic sequence). Published material is combined with previously unreported measurements to obtain reasonably accurate energies for terms with n = 4, 5, 6, 7 and 8. For the ionization limit we find the value 2 441 ± 2 kK. These data are used to calculate transition probabilities, oscillator strengths and radiative lifetimes for a large number of transitions by means of a numerical Coulomb approximation procedure.
