气压

The is related to the frequency dependent absorption cross section and the density and spatial distribution of atoms in the lower level of the transition. Position dependent 5P3/2 state densities had been combined with the collisional broadening rate 5P3/2 5S1/2 line due to both helium and cesium perturbers to yield the .The effective radiative rates of the Rb D2 line as a function of the He pressure PHe were obtained . The fluorescence intensity I780 of the 5P3/2 5S1/2 emission was measured simultaneously.

由于辐射陷获存在，有效辐射率是自然辐射率与透射因子（发射的光子在探测区域内没有被吸收的平均概率，它与吸收截面及激发态原子密度和空间分布有关）的乘积。5P3/2原子密度及其空间分布结合5P3/2 5S1/2跃迁线的碰撞增宽计算了透射因子，从而得到了不同He气压下，Rb D2线的有效辐射率。
