Plots of as a function of the atom acceleration , for time intervals and the splitting between the hyperfine energy levels: main pictures: (gray) dot dashed line: , line, splitting for transition (MHz,  MHz [53]); (green) solid line: , line, splitting of the between the and levels ( MHz, MHz [54]). Pictures in the inset: (blue) dashed line: , line, energy splitting between the levels and (GHz, MHz for transition,  MHz for transition [52]); (red) dot dashed line: , line, energy splitting between the levels and (GHz, MHz for transition,  MHz for transition [53]).
