| 摘 要： | 光学薄的Cs蒸气和低密度的N2混合系统被激光激发,激光频率调至Cs共振跃迁的两翼,CsN2分子激发态解离到Cs(6P1/2)或Cs(6P3/2)态,测量了分支比I(D1)/I(D2),这里I(D1)和I(D2)分别为CsD1和D2线的谱线强度,由速率方程分析,得到了解离率之比和精细结构转移截面。用共振激发Cs(6P3/2)态,也得到了精细结构转移截面。对结果进行了讨论。

| Abstract: | An opticall thin gaseous mixture of Cs and low-density N_2 is excited by the laser.The laser frequence is tuned in the wings of Cs resonance transitions.The excited CsN_2 molecule is dissociated into the Cs(6P_(1/2)) or Cs(6P_(3/2)) states.The branching ratio is defined as I(D_1)/I(D_2) where I(D_1) and I(D_2) are measured intensities of the atomic Cs D_1 and D_2 lines,respectively.The data analysis is based upon a rate-equation.The ratios of the dissociation rates and the fine structure changing cross section are obtained.Fine structure changing cross section has also been measured for resonant exciation of Cs(6P_(3/2)) state.The results have been discussed. |
