【Abstract】 An experimental study of the processCs (6 2P 3/2 )+Cs(6S)+nhυ→Cs(9 2D J)+Cs(6S)+(n-1)hυ is reported,where nhv represents a radiation field of frequency υ having n photons.The frequency υ is tuned in the winds of the Cs9D 3/2 →6P 3/2 transition.The branching ratio is defined as the ratio of 9D 3/2 to 9D 5/2 fluorescence.The ratio is determined for detuning ranging about 100cm -1 in the wings of the Cs9D 3/2 .The measurements show a strong sensitivity to the interatomic potentials and to nonadiabatic effects in the dissociation dynamics更多还原
