|a Transition probabilities are from the laboratory measurements of the Oxford group (e.g., Blackwell et al. 1976). b The last two columns are the van der Waals damping constants obtained by Barklem et al. (2000); is the broadening cross section for an atom-perturber relative velocity v0=106 cm s-1, given in atomic units (), and the velocity parameter, which is related to the temperature dependence of the cross-section ().|
