| Abstract: | We report here an experimental study of the process Cs(62P)+He(Ar)+nhν→Cs(92D)+He(Ar)+(n-1)hν, where nhν represents a radiation field of frequency ν having n photons. The frequency ν is tuned in the blue wing of the 9D5/2→6P3/2 transition. The branching ratios are defined as the ratios of 9D3/2 to 9D5/2 fluorescence. The ratios are determined for detuning ranging from about 100 cm-1 in the blue wing of the Cs9D5/2. The measurements show a strong sensitivity to the interatomic potentials and to nonadiabatic effects in the dissociation dynamics. |
