(a) The respective contributions of the PDM and the CRT in the energy shift of the five lower-lying energy levels as a function of α² for f = 0.05 in the resonant case, where those curves parallel to the abscissa axis represent an energy level shift caused by the CRT. The black lines: and the red lines: and the blue lines: and the green lines: and the magenta lines: and (b) The BS shift of the transition for the different α as a function of λ² with detuning δ = 0. (c) The total BS shift caused by PDM and CRT with the transition for |α| = 1 as a function of λ² with detuning δ = 0.
