Energy pooling in cesium vapor

Abstract

The total rate coefficient k for the energy pooling process \(\) has been measured in dependence on the ratio of the number densities of the Cs 6P fine-structure sublevels. The measurements were performed applying the laser fluorescence method. From the set of the obtained data for k, the rate coefficients for the particular \(\) collisions were derived. The obtained values for the \(\) and \(\) collisions at T = 600 K are \(\), \(\) and \(\), respectively. The value for k1 and the estimate for k3 are consistent with the data previously published by other authors. The rate coefficient k2 is reported for the first time.
