When the P field is stronger, such that its Rabi frequency is larger than the decay rate of level e, the fraction of f -level population that decays to the intermediate electronic state A Σu+1 can be deduced from the AT spectrum. When supplemented with values of Franck-Condon and Hönl-London factors, our measurements give a value for the branching ratio (the fraction returning to level e) of re =0.145 with a statistical error of ±0.004. The use of a strong P field on the g-e transition and a weak S field as a probe on the e-f transition results in complex line shapes in the excitation spectrum of level f, not showing the familiar Autler-Townes doublet structure.
