Abstract:
Based on two different nonempirical (calculated ab initio) interatomic potentials, we study the sensitivity of the line shape of the anomalous light-induced drift (LID) to the difference in interaction potentials using Cs atoms as an example and taking into account the real level structure in the atmosphere of inert buffer gases He, Ne, and Xe. It is found that even a slight difference in the interatomic potentials strongly manifests itself in the frequency dependence of the drift velocity in the region of the anomalous LID. The obtained results make it possible to perform high-precision testing of interatomic potentials based on experiments on the anomalous LID of Cs atoms.
