摘要
研究了Cs(6 2 P3 / 2 ) +Cs(6S) +nhυ→Cs(92 DJ) +Cs(6S) +(n - 1)hυ过程 ,激光频率υ调到Cs9D3 / 2 → 6P3 / 2 跃迁谱线的两翼 2 0 - 10 0cm-1,测量了精细结构谱线强度分支比I(9D3 / 2 → 6P1/ 2 ) /I(9D5/ 2 → 6P3 / 2 )。实验表明 。
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
