The splitting of the first and second transitions in the lutetium photoionisation scheme is studied in a wide range of laser radiation intensities, and the Rabi frequencies as functions of the radiation intensity are determined. Based on the results, we have obtained the decay branching coefficients of 0.54 and 0.41 for the first and second transitions, respectively.
