在290-650 K范围内，研究了铯原子与氘代氢、乙烷和丙烷碰撞中2 P_（1/2）Particip 2 P_（3/2）混合截面与温度的关系。 在氢和乙烷的情况下，截面的行为被发现取决于分子的氘化程度。非常大的尺寸的混合截面和同位素效应观察到它们随温度的变化，归因于电子转动能量转移的现象。
The dependence on temperature of the cross sections for 2P1/2 ↔ 2P3/2 mixing in cesium, induced in collisions with various deuterated hydrogen, ethane and propane molecules, has been studied in the range 290–650 K. In the cases of hydrogen and ethane, the behavior of the cross sections was found to depend on the degree of deuteration of the molecules. The very large sizes of the mixing cross sections and the isotope effect observed in their variation with temperature, are ascribed to the phenomenon of electronic to rotational energy transfer.
