查询词典 radiative

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 .
